I have a suggestion, make an option where you receive email notification when your credit balance drops below X.xx credits, and to make the value you receive the notification from different amounts, e.g

Recieve email notification when your credit balance drops below a certain amount: Y/N
The amount before you receive notification: 1/2/3/4/5/10/15/20/25/50/100 credits. (or something simmilar)

Even without this I have to say great job Trap17

Well I know that a version 3 of the credit system is in the works, but as for a when it will be completed is an unknown at this time due to xisto's huge growth in the last couple of years and what not, which brings me an idea of starting up a topic about Version 3 credit system.
