Ok, I can see that OB is used just like OP on other sites to refer to the 'Original Poster', but what is OB actually short for? I can't seem to find anything that states it. And it's just one of those little things that's driving me bonkers not knowing.
Are you referring to this?
In that case, it's just an abbreviation of OftenBen's name.
Otherwise, I have no idea, and I've been here quite awhile.
