There are several possible reasons why a certain user is declined to sign in to wikiAnswer. It is possible that he/she has no wikiAnswer account yet, or, if he/she has an existing account: a) the username or the password provided in the appropriate boxes on wikiAnswer login page is/are incorrect, or, b) his/her contributions did not meet the wikiAnswer's guidelines and terms of use, so the said account is probably on temporary suspension.
