Help please, to do those things (modifications or hacks)

Hi

I’m searching how to do the following things, by modifications or better by hacks/mods

1. On the registration page, add a new field where the member chose if he’s a member of a group 1 or a group 2. If the member chose the group1 (field 1) he’s a normal registered member if he chose group 2 (field 2) he will automatically register as a member of group2 (with the subscription part, see below. Of course, that’s the member who chose. For example: particular or professional could be the choice)

2. Give ranking (same way we do for a thread) to a member (with permission like which group can give ranking on which group)

3. a) Make that A certain group Can view posts, but can’t answer them, can’t contact anyone in PM or mail until he has paid the subscription.
b) This subscription will end after X months, but the member can renew it anytime for X new months.
