Yes, it's time to do some deep cleansing again. Just grabbed a fresh copy of the user and usertextfield tables, and will be doing a complete run through that to see which sigs need to go, or be trimmed.
Basic Rules of GFY
2. Signature rules. Maximum 120x60 button and no more than 3 text lines of default size and color. Unless your sig is for a GFY top banner sponsor, you may use a 624x80 instead of a 120x60. Yes there is a reason this is so big. Also putting your text in a cell and making it look like a button is against the rules. Let me repeat... A 120 x 60 button and no more that 3 lines of DEFAULT SIZE AND COLOR text.
