I Will Be Making GIF Signatures For People Here is Mine Start Requesting Below -Please Put A GIF You Want Edited
OP - while it's a nice gesture, please consider the quality of the user forum experience before giving everyone a gif signature. Imagine if everyone used one, it would slow down loading time for each page quite a bit. Plus it'll use more data, which isn't cheap.
I although like signatures, have to agree with IC. Any signatures I feel should not be animated for the reasons specified a simple, yet awesome static signature would work fine, but make sure it's optimized for the web. Gifs alone animated or not carry too much data within which is really useless and eats mobile data as well. Just an optimized .jpg or .png (if wanting transparent bg) works awesome
