GuildWiki does not collect any personal information about users. We don't even require an email address when you create an account. However, you can later add an email address to your preferences - this email will not be shown to other users, it will only be used by the MediaWiki software if someone uses the Special:Emailuser form to send you a message. For a more formal treatment of this issue, please see Wikia's Terms of use policy (GuildWiki is part of the Wikia network).
