As part of a web development project for a client of Kosada I created the OG Titles module to allow the assignment of arbitrary titles to group members. This is a basic module with Views 2.x integration where you can make some neat member list pages with titles attached.

Although I maintain several svn versions of this module for private sites the public versioning system is Drupal CVS.

Organic Groups Titles is a simple module that allows you to create arbitrary member titles for each membership of a group.

Usage:

• Clone an og view such as og_members or og_members_block, and add in the member title field.  Or create your own 'member list' view.
• Group managers can manage member titles by going to og/users/%/titles where % is the group node id.

That's it!
