I noticed that only two people are using a theme other than the forum default...and I'm one of them!
Just in case you weren't aware we
had other themes you can use, and are curious to see what other themes we have and what they look like, here's how you do it. Go to your
profile -> Look and Layout Preferences -> Change (next to "
Current Theme" at the top). This will show you the other options and let you preview them, then change to any other theme you like.
If you WANT to go with the default, then that's perfectly fine, of course. But the fact that practically EVERYONE is using the default leads me to think that many folks just don't know any better.
Oh, and if you find any other SMF forum themes on the net you think would be good here, let Kralik or I know and we can add them for you. Variety is a good thing, so long as we don't go overboard and end up overloading the server with tons of theme options!
