Take it Easy Man, Well .. I'll just won't some more bucks monthly and I thought it was BAD to have links from sigs ?!? (Maybe I'm a Noob?!)
Kill yourself over loss of inbound links? I think a person have much more to live for than a few web site and a copy of inbound links. Taking out the sig links will be a pity but it is just a blip in my life, nothing great.
It would be a catastrophe. Imagine all the posts, which you have your links placed on it getting removed and all are gone just like that.
