Angel, there is already a black theme available in the theme chooser at the bottom left (I mentioned this in the logo thread in response to your previous request). It's not consistent with the current white theme, but it will do while I work on the dark version of this theme.
As far as removal goes, they didn't remove Zoopy's sig image, just the server IP. Although they didn't remove my IP, I just took it off voluntarily. Both our sig images are still there.
As far as the sig image goes, I'm going to have to just go ahead and keep it the same as it is. I'm just too short on time to make revisions, so you'll have to trust my artistic judgement on this one
Don't worry, I won't be offended if you don't like it. I'm tough like that.
