Currently you can go up to 80 or so lines in your sig (one character per line), because it seems that sigs are mainly limited by # of characters, which is pretty silly as could lead to the forum getting pretty messed up if some clowns decide to abuse it.
Plus over 10 lines in a sig isn't really necessary anyway, not even for listing system specs.
