You may have noticed that the look of the forum has changed

I've installed 3 additional themes, one of which (called Ig-Oh) was set as default. One more, AppoloBB, is also very good and might be set as default as soon as I change the logo. Anyway, you can already select any of those 3 themes for your own usage, as well as revert to previous theme setting, or choose another pre-installed skin that was available before the current change.
To do this, enter Profile -> Look and Layout Preferences. On top of the page, you'll see your current theme and "Change" link. Click it, and choose the theme you like best (there are thumbnails next to each theme to give impression how it looks like).
Enjoy!
Note that changing themes is available only for registered users. For guests, default theme is always used. Any feedback or comments may be posted in this thread.
