difficulty with chat

Hi - just installed chat but it seems to have buggered up my twitter feed (see footer on front page) - plus the box is too big on the front and is not resizing for some reason and it goes behind my slider and there doesn't seem to be anywhere for me to write an intro message telling people what to do. Not too impressed so far I have to say. Please advise.
