Alright, we were talking about the possibility of changing the default skin. (The skin that shows when you are not logged in, also the one that shows if you haven't specifically overridden it).
Post your decision in the poll above.
The current default is New Terra (the dark red/purple one that looks otherwise similar to the regular IPB Skin Set).
Default skin change won't affect anyone who has specifically overridden the defaults.
If you want to change your defaults, simply go to "My Controls" on the menu bar, then on the left side pick "Skin and Languages" to set your choice. You can preview them all from there as well.
Thanks, op2hacker.
