No, you cannot delete your account. Harley, the webmaster, and Aimee in Wonderland, the Acting Head Forum Mod, have the power to delete accounts - but they are very rarely deleted, and usually not just because a member has lost interest in the site. Depending on why you no longer want your account, there are a number of alternatives, such as changing your name and / or simply leaving the site.
You are also welcome to contact the moderators on
