But as far as them being real money, no, they are not. They are a forum addition that you can transmute into money, and buy things with. (Even real life things)
Im going to buy hosting .com for a year with 7 dollers thats why i neeeded to know Merged Post: Could someone donate me 100 credits
You can eventually sell your credits to someone on the forum when you have large qualities ( people don't usually buy less than 500, but its not impossible), for a going rate of 1$USD = 200 Credits. The Admins and Moderators do usually look down on this because they can't help if someone gets scammed but its no illegal or against the forum rules. Untill then, Credits are for buying things like Signatures, PSDs, Tutorials and Services ( such as rendering)
To be honest it would be much easier just for you to scrape $7 together some other way. Making 1300 posts here may take you a while.
