Ye' old general discussion board. Basically, for everything that isn't covered elsewhere. Come here to shoot the breeze, shoot your mouth off, or whatever suits your fancy. This forum is not for asking programming related questions.
Check out Dia. It is a GTK+ program, so it's native to Linux, but there is a very functional windows port of it available - you can google for it if that's what you need, or I think there's a link in the referenced page. Let me know if it works out for you.
