Syndicate Out syndicates all posts made in a specified category (or optionally all posts) to any other WordPress 
blog(s) in real time. This enables blog owners to create automatic aggregating, or topic specific blogs from any 
number of different blog sources without relying on RSS feeds or any kind of timed events. Put simply: it re-posts 
the content of one blog to one or more other blogs.
The plugin uses WordPress’ built in XML-RPC functionality to push posts to the target blog. XML-RPC will need 
to be enabled on the receiving blog in order for this plugin to work. For versions of WordPress 3.5 and later 
the XML-RPC is enabled by default. For versions prior to 3.5 it will need enabling in the admin panel.
For versions 0.8 and higher of the plugin the sending blog needs to be WordPress 3.1 or higher due to the use of 
the WordPress enhanced IXR client, and the receiving blog needs to be WordPress 3.4 or higher so that the XML-RPC 
WordPress API posts functionality is available.
More information is available, feature requests and bug reports are gladly accepted over on the 
<a href="http://www.flutt.co.uk/development/wordpress-plugins/syndicate-out/" rel="nofollow ugc">project’s own blog</a>.

This plugin adds the ability for users to create new bbpress forum topics in multiple BuddyPress group forums at the same time.
Users will only get one email notification about the new topic, even if it’s created in multiple groups that they’re a part of: a notice added to the email lets users know what other group forums also had the new topic posted to them.
Users will also only see one entry in their activity feed. Similar to email notifications, information is added about the other groups where the topic was posted, if the user is a member of or has access to more more than one of those groups.
Initial attachments and topic tags are copied to all of the created topics in each group forum. The topics aren’t linked beyond that though: new replies and attachments, changes to topic status, etc., will only affect individual topics, not all of them.

BP Multiple Forum Post

Lets users cross-post a new bbpress forum topic in multiple BuddyPress group forums.
