>I still do not think there should be any limitation of what goes in the signature (other than the rules of the forum of course). It becomes an issue when a signature ONLY has links and there is no way to tell it is part of the signature and not a part of the message. Frankly, I've never even noticed it until today and then on only one user's messages.

Yes, it is the same thing to me. I noticed it when it was referenced here in this thread.

I think adding some validation, in case a signature only contains links might do. For example, would be there a purpose to create a signature with only a link? Basically, a signature has to contain something useful in it I guess. But, if there is only a link, I thought that maybe I could validate that and suggest the user to enter something more in regards to a signature.

Is that something you think could be better?
