So.
If the suggested hack, were done sorta like this, I for one would use it.
If the invite code was setup, so I could use the "usergroup restrictions" when I sent the invitation.
Also if there could be serveral invitationcodes like below, so I could use them sort of like this:
MCSE forums = invite code 0001
Costumer forums = invite code 0002
extremely illegeal software forums = invite code 0003
(Sorry couldn?t help myself

)
Then the invited user would reg him/herself and ONLY have access to the forums that he/she was invited to, and all other forums would be "private".
Also a "read only" option would be cool, so I could invite a user, but he/she couldn?t post, only read, and perhaps with an exploration date, so if a user paid for 14 days of usage, the account would automaticly expire on a preset day....
Ehmnm... I have a lot of other ideas to this, but i ?m not sure if I?ve explained the above clear enough to continue??
