I went to change my signature earlier, just a minor change, changing my warlocks level. Apon trying to do this, I got an error that the font size I'm using is too large. This is the first I've encountered this error in the long time I've used this signature (must be well over half a year). I've edited it many times without problem, but now it seems it wont let me anymore (or well, I'd need to make the font smaller).
So my question is, has there been changes to signature regulations?
