This article is going to take you through setting up BuddyPress for the first time. It is geared towards people trying to set up Social Networking sites with features similar to those available with Ning or other hosted Social Network providers, as such it assumes that you will want all of the features of BuddyPress, plus a few more (well, a whole bunch more!).
BuddyPress Activity Filter is a useful plugin that allows you to customise the the way the BuddyPress activity feed works. It allows site admins to limit which filters are available on the activity page, limit which activity filters are available on the main site-wide activity page and customise the activity updates for each post type.
This is a simple plugin which allows the BuddyPress Admin to enable blog post updates to be advertised in the BuddyPress Activity stream. By default, notifications to the Activity stream only happen on new post creation, if the post is then updated later, there is no activity update and your sites users will not be informed of the changes. This can be discouraging to your authors looking to inform site members of changes to published posts. BP Add Post Updates to Activity fixes this.
