Due to spammers registering here, not posting anything, and making spam links in their signature, we have had to implement a change in user permissions.
Starting now (17 July 2008), users will not be able to add profile information including a signature until they have made more than 10 posts. In addition, guests to the site will not be able to view any user profile. This second restriction may be lifted in the future.
Sorry for the inconvenience, and blame the spammers who ruin things for everybody.
