Dunno how many of these you have bookmarked, but these are places I check a lot:
Peter's Kite Site: http://www.win.tue.nl/~pp/kites/
specifically the tricklists
alphabetic: http://www.win.tue.nl/~pp/kites/basics/ ... x.frm.html
functional: http://www.win.tue.nl/~pp/kites/basics/funcidx.frm.html
But also contains kite plans and a whole load of stuff.
Gone With The Wind forum http://www.gwtw-kites.com/forum/default.asp
It's a Seattle based store, and has a rabid prism following, and also a rabid anti-prism troll faction. But it's mostly just good advice and chat. Very active.
