In other words, the visibility of signatures could be turned "on" or "off" for that particular user. All my other members enjoy seeing the signatures, as well as using them, so I would be hurting the majority in just disallowing signatures from the forum as a whole.
Yet, why should this one member have to put up with the sigs if they annoy him and make his forum experience more difficult and make him less likely to enjoy my site?
What do you think? I'd love to have your feedback.
