Anyone know how to create a proboards theme in gimp? I ask because I'd rather do that then use the theme creator that's included with the forums.. you know, change it up a bit.

To save a theme, the file extension is .pbt

It isn't possible. Neither GIMP nor any text editor can read files with a .pbt extension. I downloaded one of their themes and tried to open it with a number of programs. It isn't written in any standard coding language. (HTML, CSS, JS, XML, etc.)

All I was going to was try to create a theme and save it. I can't even do that. It sucks that it's not possible.
