Thank you for your reply and explanation, Shawn. I figured that the Bio meant exactly what you said, but I wasn't 100% sure. I will check it out in a minute...
As for the signature, I understand your concern for spammers and it's nice to know that you take precautions. I was only wondering, because it is given as an option, but it can't be applied.... so I was asking myself ...why...? Once again, thank you very much for answering my query and for explaining the circumstances.
Kind regards, Maria
