Sponsor Groups on Forums

[Teg]

I was just wondering if anyone has a sponsor group on their forum. A sponsor group is a group that members have to pay a certain amount of money, either one time or per year, which gives them special perks aside from other members. Do you guys have anything like this on your forums? If so, how much do you charge and how often? What are somethings you offer? What do you use the money for?

Currently, I do not have anything like this set up on my forum, but it is in progress. I plan to charge 10$ a year per person for the sponsor group. The group as a whole will get a username color, then individually, they will be able to change their username when ever they want to, have a custom thread title color so it stands out from everyone elses, and lots of other things. Mainly the reason for the group is to fund things for the forum itself such as the domain name, ad-free since it's a free forum host, maybe even payouts for contests at a later date.
