I'd like to have a discussion about this. I just noticed Lord Dave's sig consists of
a post from CN, which would normally likely not be allowed to be posted in the upper fora. However, since it's been quoted in a member's sig, it can now appear prominently throughout the site, including the pages accessible to unregistered users.
Of course, as it stands, doing so is not in breach of the rules, but perhaps we should do something to restrict sigs just a bit? To me, it looks like the lack of regulation in signatures is an oversight which allows for some rules to be partially circumvented. I'd be curious to see what others think.
