I pretty much think the forum would fall apart a bit, become worse than it is now. TE would acknowledge this and promote Chewbaka to become the new owner and actually give him the access he's been waiting for (lol).
People will rage, mistakes will be made, Mike will come back eventually after people rant and harrase him for leaving on skype.
If that doesn't happen, things would -maybe- cool down after like a week or two. I'm also shocked nobody has an input on this subject.
