Glad you like it, Sajid.
For anyone else that doesn't know what we are talking about, you can pick any one of the forum layouts in your profile section, instead of looking at the same one all the time. Just go to your profile, then click on "Look and Layout preferences" and you will see "Current Theme: Nucleus (Change)." Where it says "change" you can click on that and select your own theme.
The only thing is there will be some things missing, as Sajid had said. I wasn't sure if we were going to use the other themes so I didn't code the other themes to have the Gallery and Chat room, and some don't even have the banner at the top. So, I put them there for you to use, in case you guys get bored, but if you want to use all of the features, you will have to use the default theme for now.
