I think it's a very good idea. This is a security site, so there should be more about securing anything, so you don't have to ask each time or search the forums to hell. Maybe it also would be nice to sort out the tutorial forum (negative, I don't say you should do it ), put the original ones that actually cover something about security in that.. whatever it is. So don't only keep the stuff inside a DoS topic...

Well. maybe that's a bit to much revolutionairy and much work...
