Shows dedication, better userbar, access to higher tier items, basically a replacement for VIP. One day you won't have to pay VIP if you're all the way at the top!
Shows that you are a trusted member most of the time.
Also it gives you access to the programs.
VIP is for VIP only and believe me, you want VIP for when the good shit get's released.
Also we can give more rep.
That depends on the Rep power
100 Rep = 1rep power
1000 posts = 1rep power
I mean information, when the item glitch was released, it was for VIP only, also certain services and deals VIP exclusive.
Mainly programs are awesome though.
Plus VIP supports the site!
Some day there will be a truly awesome program made for VIP and created by myself! And ranking up to official clraik also lets you see who repped you
