A good website that has friendly people and interesting games in the process of being made. It more centers around RPG Maker 2000-2003 than XP, but all the same it's a good place. Check it out if you can.

I'll check it out cuz more attention to 2000-2003 than XP is something you don't find on every forum.
This site is really fresh! But it contains the coolest RM2k/3 animations available.
