I found the old thread. I said it then and I'll say it again... I still haven't seen any whoppers so haven't a clue which ones the OP is referring to and how they managed it. :lol:
If you see any excessively giant sigs report it an we can take a look. Unfortunately, the sizing program is automated, so whilst we'd let you get away with a px or two over it will be strict over the size even if its not far out.
Also, if signatures bug you or make it hard to read the forum on whatever computer/phone you are using, you can turn them off so you can't see them. If you go into your user CP and then 'edit options', somewhere about half way down the page you can un-tick a box which says 'show signatures', and voila!
There's no way I'd be such a hypocrite as to have my own signature but have everyone else's switched off
