I am the captain of a guild called Were-Animals, which specializes in information related to Were-Items (aka "I am" items). It's not as up to date as I would like it to be, but hopefully I can refine a method to speed up the process of updating it in the near future. Still, it's probably one of the biggest Were-Item databases currently available.
I've made a list of the animated GIFs found around Gaia in my List of Gaia’s Animated GIFs thread. The newest GIFs will probably be towards the end of the thread, if you're looking for links to them.
As a hobby, I also like to edit and make the GIFs, though I'm not as good about fulfilling requests anymore. I have a list of the GIFs that were made by regular users (including my own) in the User-made GIFs section of the thread. Check the GIF Artist/Editor section under the image to see who made/edited the GIF.
I have a few petitions on Gaia, but currently, my most popular petition is STOP releasing gold generators! with 1,800+ signatures.
