With the hopes of giving visitors a one stop shop for finding prior contests that I have held I have created this thread.
Added by Palomine: the moderators ask that users/fans of Carl's excellent morph contests PLEASE DO NOT REPLY IN THIS THREAD so that it can remain a concise listing of all the previous contests. Thanks.
