Maxtor you are inactive as an admin for a long time now, you didn't look like you care about the MxC at all. Everybody got tired and quited cause of your inactivity and some wrong-picked promotion maybe as well. Some other left cause they were butt-hurted cause they didn't get a promotion and the story goes on and on and on. What you need here isn't just staff changes, what you have to do is to advertise forum & provide something fresh & unique. Gaming forums ain't that popular anymore...
And about that thing that you want to turn donate members to 6 months then give me my money back! I paid for a Lifetime Donator Member Permission, which isn't something big after all as VIP/Donator Sections are pretty much dead. If that happens, I want a full refund as I paid for something else and I will get something different after all!
You need to find a way to make people buying actually VIP/Donate subscriptions, you need to find a way to make these ranks attractive.
