Membership incentive hacks?

[origin8or]

I would like a way to offer various grades of membership on my forum and wanted to know if there was a way to offer things for paid memberships like:

- larger avatars
- no signatures for unpaid members
- increased signature lengths for paid members
- allowing photos in signatures for paid members
- increased PM limits
- personal galleries for paid members (I use coppermine)

Where these options can either be turned on or off by the admin, or by placing paid members in specific member groups, depending on the membership status selected?

If there are any mods already out there, let me know... If it's all custom stuff I don't mind paying to get some help on this - let me know. But I think it is a model that many smf users could benefit from.

I would check out the paid subscriptions mod and combine it maybe with the Shop mod I think you can accomplish most of that in the post you made with those mods.
