I think you should add a theme changer on the index page like v bulletin. for an example go to mmorpg4free.com/forum

Not really a default feature that should be included.

But I found a mod that does this

I have got over 40 themes on my site.  It won't show up on custom made ones.

I want to have something like this.

I think I have seen couple of threads around on SMF site. Anyone know how i can get this work?
