Seriously, the site needs an overhaul design wise.
to be fair to 13th_Star, so does myspace. only difference being myspace did it first in terms of social networking sites mixed with bad HTML - so that was its "quirk"
doesnt mean i like what myspace have done though....
personally, i think that "theming" pages should be slightly limited somewhat, rather than allowing full out and out going to town HTML butchery. it's been done now, so time to move on. I can appreciate the work that would have gone into your site so far, but i think you need to change its direction/image slightly to move AWAY from myspace a bit - otherwise, well - might as well just use myspace. the music scene is good on there too - albeit all kinds of music.
i'd say it "will do for now" - and as you've got a fair few members, ripping it down and starting again isnt really practical - but maybe it's worth putting a bulletin or something out to them too and see what
they say.
i'd start probably by making the communal pages more readable and less myspacey, and leaving the dodgy HTML to the member pages.
good luck
