I am no expert in design, but the front page has a lot of empty spaces. I think things should be condensed a bit. THREADS is written in huge fonts, then we have number of threads showing (why the fuck is that important), we have a line at the top with nothing but the username and logout, another line for search... I liked it more in the old SC, where things were more condensed and I could see more threads instead. You know, get more info on the screen, instead of all those empty spaces.
Also the private chats are called "/tell X". A bit weird, they should just say "X".
