I noticed that alot of users are signing up with their e-mail addresses as their usernames, I don't know if this is done as an error or otherwise, but there are various points you should be aware of - Alot of search engine spiders visit this site, so it is guaranteed that this email address will be harvested and used to distribute spam junkmail. - It looks messy? vBulletin protects email addresses from these harvesters by using a built in form and we will never ever sell or give your email addresses to anyone, of course. If you wish to change your username, please contact myself or one of other Administrators. Anyone is free to change their e-mail address, but I always ask our older members to make a reference to their old username as a courtesy to everyone else.
