I will always spend the last 2 weeks of every major build fixing as many bugs as I can. The problem is, I don't always find them! This is where you can help :) Post any bugs you find, and if you can, any events leading up to the cause of the bug. This will help me crack down on them.
Also you can post your suggestions for future ideas here. I may not get to them right away, but if I like your idea then I may incorporate it in the future and credit you :)
