Differ How about y'all contribute to the comp.tf wiki. There's a lot of stuff that needs updating on there, but there's no need to reinvent the wheel.
I probably will end up doing that, but the issue I see with the wiki format is that for a new player going to comp.tf for the first time, it can be pretty confusing as they don't know where to start. Along with that, while comp.tf is a great resource for information about the game, it's not really ideal for people who want to get started, but are either confused about how to do it, or are afraid/intimidated to do so (the latter is more common than most people think)
What I had in mind was something like playcomp.tf, but far more in-depth; playcomp is a great resource because it's very simple to navigate and presents the information in an attractive and easily understood way. Personally, I think we need a resource that has the information that people need as well as directly addressing the concerns that new players often have. Comp.tf is an invaluable resource, but it serves as a reference tool, which is great, but I think we need a quality teaching tool.
