Over at Rift Crafter (
http://www.riftcrafter.com), I've set up a repository of AddOn resources. Some of them are external links to Rift icons, the fansite kit, but I've also included links to resources that would be useful for editing Lua or viewing DDS files (the format Trion stores icons).
Check it out over at
http://www.riftcrafter.com/index.php...velopment.html and let me know what you think. If you see anything that I should add, just let me know.
