I don't do a whole lot of plugin/coding, but I see you are using the 'showthread_postbit_create' hook and trying to use $post['userid']. I'm not sure that you can talk about a $post['userid'] in that particular hook location. Maybe try using one of the postbit hooks?

(Like I said, I could be totally wrong, but thought I would throw this out there just in case.)
