At the moment we r getting 6$ per month through free credits but a sever supporter gets 7$ per month(*Support the Game by paying 5$ of the Hosting Costs each month You get 7 credits every month*)
In order to have balance between a supporter and a non-supporter Requesting to raise the free credit amount by 1$ by increase certain important add links by 0.02 isn't of 0.01 Thanks.

Any increases to the amount of money you get from free credits, is a decrease in the revenue generated. Surely the fact that its nearly on par with the lower levels of subscription is already pretty decent? Compared to some games where you have to pay $$ to send messages to others!

Won't happen.

Chewett mentioned part of the reason, but there are other plans that will change free credits (hopefully we might see that this year)
