There have been a lot of great ideas for support systems, whether they be simply an IRC channel or forum, or a bug tracking system like launchpad (or one of the other thousands out there). They all have their own pros and cons, and often times I've seen problems bounce back and forth between them because while each solution works, they aren't always what you want at that time, but they may be 10 minutes later for the same issue. So, after some idea bouncing today, I came up with an idea, a hybrid support system.

Remember, for every $5 or greater donation you get to request how-to/tips'n'tricks list/similar article written, so what are you waiting for? (Keep in mind the effort involved in your request compared to the money you've donated, I'm not writing a guide to all the gcc options for $5).
