hi there! 
i've spent the last few months adding to and updating all sorts of articles on wikipedia. with the help of others, it's turning out quite well if i do say so myself.
have a look at, and edit if you wish, all the fiends, gods, planes, and more!
Competiting with us are ya, Boz?!
*grin* And yeah - I think there's at least a few posts on Wiki that need some planar input on them... too much anti-Planescape bias in some of those posts for my taste.
