Invite Anyone is a BuddyPress plugin that adds a widget allowing site members to invite friends to join the site via email. It also changes the behaviour of group invitations meaning group members can invite non-friends to join the group.
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.
