Agree with your point. But the same text in the sig as me was as a step too far.....and could lead to someone mistaking me for him or vice versa.
e.g. when you know you've seen a post and then forget the users name but remember the avatar...then stumble across a post at a later date and think ah-ha...that's the guy.
Thought he'd amended his sig...but alas no. I know he's received my message as its in my sentbox
