This is a request for a hack to allow users to have multiple signatures - up to an admin defined limit, and for the user to have a dropdown box when posting to select the signature they wish to use. If left unselected, the default or first signature is used.
I second this request. I think it would be quite a useful feature to have, for my forums, anyway. In addition, if possible, it'd be nice to have an option to use a random signature if none is selected.
