+[h3]Project Overview[/h3]
 
 $Projectname is a decentralized community server providing communications, identity, and access control services which work together seamlessly across domains and connected websites. It allows anybody to publicly or [b]privately[/b] publish a range of web/media/personal content. The cross-domain privacy implementation is unique and somewhat revolutionary, as identity and access rights are negotiated by servers invisibly in the background.
 
+
+$Projectname provides distributed web publishing and social communications with [b]decentralised permissions[/b].
+
+So what exactly are "decentralised permissions"? They give me the ability to share something on my website (photos, media, files, webpages, etc.) with specific people on completely different websites - but not necessarily [i]everybody[/i] on those websites; and they do not need a password on my website and do not need to login to my website to view the things I've shared with them. They have one password on their own website and "magic authentication" between affiliated websites in the network. Also, as it is decentralised, there is no third party which has the ability to bypass permissions and see everything in the network.
+
+$Projectname combines many features of traditional blogs, social networking and media, content management systems, and personal cloud storage into an easy to use framework. Each node in the grid can operate standalone or link with other nodes to create a super-network; leaving privacy under the control of the original publisher.

+$Projectname is an open source webserver application written originally in PHP/MySQL and is easily installable by those with basic website administration skills. It is also easily extended via plugins and themes and other third-party tools.

 $Projectname is free and open source.  It is designed to scale from a $35 Raspberry Pi, to top of the line AMD and Intel Xeon-powered multi-core enterprise servers.  It can be used to support communication between a few individuals, or scale to many thousands and more.

There is currently no official mechanism to contest or reverse this decision, which is why you SHOULD mark your own account NSFW if it is likely to be inappropriate for general audiences.

+[h3]Features[/h3]
 
 $Projectname is a general-purpose web publishing and communication network, with several unique features.  It is designed to be used by the widest range of people on the web, from non-technical bloggers, to expert PHP programmers and seasoned systems administrators.
 
 This page lists some of the core features of $Projectname that are bundled with the official release.  As with most free and open source software, there may be many other extensions, additions, plugins, themes and configurations that are limited only by the needs and imagination of the members.
 
-[h2]Built for Privacy and Freedom[/h2]

 You have the ability to control precisely what appears in your stream using the optional "Connection Filter". When enabled, the Connection Editor provides inputs for selecting criteria which needs to be matched in order to include or exclude a specific post from a specific channel. Once a post has been allowed, all comments to that post are allowed regardless of whether they match the selection criteria. You may select words that if present block the post or ensure it is included in your stream. Regular expressions may be used for even finer control, as well as hashtags or even the detected language of the post.

 Access Control Lists work for all channels in the grid due to our unique single sign-on technology.

After that, authentication to all $Projectname resources is "magic".

Birthday events are automatically added from your friends and converted to your correct timezone so that you will know precisely when the birthday occurs - no matter where you are located in the world in relation to the birthday person. Events are normally created with attendance counters so your friends and connections can RSVP instantly.

 You may create any number of personal chatrooms and allow access via Access Control Lists. These are typically more secure than XMPP, IRC, and other Instant Messaging transports, though we also allow using these other services via plugins.

 $Projectname has many "Content Management" creation tools for building webpages, including layout editing, menus, blocks, widgets, and page/content regions. All of these may be access controlled so that the resulting pages are private to their intended audience.

 Apps may be built and distributed by members.

 Our implementation of privacy groups is similar to Google "Circles" and Diaspora "Aspects".

You may over-ride this at any time (prior to sending the post).

 We provide easy access to a directory of members and provide decentralised tools capable of providing friend "suggestions". The directories are normal $Projectname sites which have chosen to accept the directory server role. This requires more resources than most typical sites so is not the default. Directories are synchronised and mirrored so that they all contain up-to-date information on the entire network (subject to normal propagation delays).

 For $Projectname hubs that use TLS/SSL, client to server communications are encrypted via TLS/SSL.  Given recent disclosures in the media regarding widespread, global surveillance and encryption circumvention by the NSA and GCHQ, it is reasonable to assume that HTTPS-protected communications may be compromised in various ways. Private communications are consequently encrypted at a higher level before sending offsite.
