I think that the ability to see all IP addresses used in post's by a single user like in UBB.Classic would be a plus again since many community users interact from both work and home. This would stop many administrators from pulling out their hair on IP banning and then seeing that the user has more then one IP they have used many times.

Also add a way to edit subscriptions length and manual stuff for an admin since not everyone's servers are compatible with the paypal ipn system. This would allow you to manually approve it and set the time limit or edit the time limit and such. This is a must as far as I can see.
