Administrators can allow users to add other users to their buddylist and use that to track their most recent posts.

1. Make sure the Buddylist module is enabled by clicking administer » modules and making sure that the box next to buddylist is checked.
2. Click administer » users » configure tab » permissions to configure the permissions for Buddylist:
• maintain buddylist so that users can add and remove users from their Buddylist
• view buddylist so that users can simply view users' Buddylists.
3. Click administer » settings » buddylist
4. Choose a number for Number of buddies to list in the user's buddy block.
5. Choose a number for Number of posts to list in the buddies' recent posts block. This is the total number of posts a user will see, so if a site is particularly popular, a small number might mean some missed posts.
6. Type in a Block title for the recent posts portion of the buddy block. This is useful if you want to call the list something other than "My buddies' recent posts".
7. Choose a number for Number of buddies and users who've added me. This is a global setting for all users.

The Buddylist block is well-suited to being "custom", that is a block that users can choose whether or not the buddylist block appears on pages for them., See our documentation on enabling and placing sidebar blocks for more information on how to configure blocks this way. With the module enabled and permissions set, each individual user can view their buddylist and add and remove users to it.
