I've PM'd at least two mods (cant remember who offhand) and mentioned it in the last post about big signatures, but there is still at least one user on here sporting this signature......
It tips the scales at 1,862,664 bytes, which is a little over the 25,000 byte limit I think (like 700%!!) and I do certainly notice threads that have it in load much slower.
I don't want to publically name the user, but I'll give you a clue.....
