Here are a few of the alternate ChatStyles available on github:
- PanamericanaMini - this is probably the first alternate ChatStyle. It’s very similar to the default Panamericana theme, but with some whitespace removed.
- Brief - nice theme. Check out the screenshots.
- My fork of Brief on github - I like the Brief chatstyle, but I made some small modifications to further reduce extra whitespace and I modified colors slightly.
- Simples - heavily influenced by the Renkoo style for Adium. Screenshot.
- StyleShift - reduced whitespace, every image URL is expanded in a linked thumbnail, custom emoticons.
More ChatStyles are available in Skype’s ChatStyle Gallery. They’re also running a competition, so you can go vote for your favorite.
