I'd like to see a very diverse set of what can be accessed by paid members only (if the admin so desires). Things like:
1) Advanced search
2) WOL
3) Signatures
4) Avatar (or avatar size)
5) number of pm's stored
6) the blocking of certain CI's (when used to house ads etc)
7) Poll creation
8) Attachment access or addition
9) screen shots attached to post show as thumbnail unless you are in the right group (paid or not as set by admin)
This should give ya a good idea
