 * Hiya! Are you sure that you are filling in all the fields at Special:Signup, and have a free username and the passwords are correct? If so, please report back. Mark  ( talk ) 19:39, June 12, 2010 (UTC)
 * Most likely you're entering your birthdate as something indicating you're under the age of 13; Wikia requires those who create accounts to be over the age of 13 (see the terms of use). You may want to contact Wikia staff and explain the situation if this was not the case. Joey (talk) 19:42, June 12, 2010 (UTC)
