Sponsor Fees

If I want to keep my post for the highest listed, Erik mentioned from his post that I must sign up as a sponsor. I tried the link: http://www.mbsonline.org/forum/sponsor.asp, but it doesn't work. Also, if somebody can tell me the fee to be a sponsor and the features at the different levels, that'd be greatly appreciated.

Many thanks.
