WikiaBot is a new puppy here at Wikia. We hope to train him up to check out some of the basic functions on the site. He will log in, create pages, request wikis, and then report back to us on any problems he finds.
Hopefully you should only see him when he edits your wiki or creates a new page. He will also clean up after himself.
However, he is still a beginner, and may sometimes be a naughty little pup. If so, please let us know and we will discipline him and clean up the mess.
