There have been a few recent sign ups on this site with the sole purpose of creating a backlink to another website, these users then promptly leave the site never to post or add to the forums. We consider this practice as SPAM and delete these links and ban these members! As a rule we do not allow spam and this involves creating links within the signature space. However, well known and active users are given leeway here and we are happy for those users to add a link to their signature for their own website or blog.
