If you received a welcome message from me, it's probably actually from an automated Wikia bot, User:Wikia. I'm still happy to answer any questions you might have, though.
I operate my own wiki bot, User:Supermorff Bot. Any questions about it or its function should be addressed to me.
I also write fanfiction, but I do it at FanFiction.net (the site designed for that sort of thing) and not here. Some of it is even Sonic-related, although only two of those have been posted. The first, "Schemes and Plans", is set in the Sonic X continuity and is mostly my own theorising about the Ultimate Lifeform. The second, "Tails' tall tail tale", is in the games universe. It is a short story in which Tails wakes up to find he has inexplicably grown a third tail overnight. If anyone's interested, you can find them through the link above.
