There are a few sample themes loaded that you can switch to and look at. These are just a couple of themes that we might pick to be the "real" theme eventually.
To change your theme:
Go to your [a href="vny!://discoverseattle.net/forums/index.php?action=profile"]Profile[/a],
In the left column, click on "Look and Layout Preferences",
Click on the 'change' link at the top under "Current Theme: Forum or Board Default (change)"
Select "preview >>" all the way on the right side across from each theme.
If you like it, select "Use this theme", then you can bop around and see what stuff looks like. You can always go back to the Default theme (and you should after you're done playing around).
You won't see any real change with the first couple of themes, so try the ones at the bottom.
