I kinda like it. The colors aren’t my bag, but neither is glam rock
I would add some padding to the bottom, to get the black on the blog or the white in the forum to extent below the bottom of the content a little bit, to “frame” it.
I think the padding would be added to the #main div on the forum. In the blog, I’m not sure since it’s a table layout.
Otherwise looks like a nice forum, lots of activity. Nice job.
