//service class configure in .htconfig.php:
$a->config['system']['default_service_class']='standard';  // this is
the default service class that is attached to every new account
$a->config['service_class']['standard'] =
array('photo_upload_limit'=>20000000, // total photo storage limit per
channel (here 20MB)
 'total_identities' =>5, // number of channels an account can create
'total_items' =>2000, // number of top level posts a channel can
create. Applies only to top level posts of the user, other posts and
comments are unaffected
'total_pages' =>10, // number of pages a channel can create
 'total_channels' =>500, // number of channels the user can add, other
users can still add this channel, even if the limit is reached
 'attach_upload_limit' =>20000000); // total attachment storage limit
per channel (here 20MB)
