Up until now, the only limitation on forums signatures has been a set number of characters, however, recently there have been a lot more signatures which have used oversized text or lots of line breaks to take up a lot of space. This situation now requires a new rule on signatures be implimented:
signatures will be limited to 5 lines total including spaces, and no signature may use an overly-large font size.
Different fonts have different sizes, but the general rule of thumb is that size 4 is the top limit.
Any signature breaking the rule may be deleted without warning.
