When you insert an url in your post, the whole URL info goes into the post making it a lot more difficult to read and edit. It's the same in the signature, a bit anoying to edit those when they are filled with code, even when you know HTML.

Is it possible to avoid this - can't remember it being like this before the update?

And now we're on the subject of signature I believed I punked RobA for the possibilty of not counting characters when you make the signature since it counts the HTML characters as well. I believe an honor system off max 5 lines or 80 pixels (just an example) would work beautifully.
