The spacing is indeed a problem. It's a win some at one end, lose some on the other sofar. A skin like Eidmubarak always shows one column. The normal skins take as much as they can get and it looks ok in some cases, in others it doesn't.

Different forums and filters are one problem, different browsers and screenresolutions are another. A list tag is used and that 'adds' a br I think. I'll try some tweaking in the experiemtal skin to improve it.
