Step Two: Move or create a toon on a low pop realm and create a guild. You can call it something like "Pre BC Raiders". (Probably a PvE realm so all can transfer to it.).
Step Three: Start a website, Call it something like "PreBC-RAIDERS.com".
Step Four: Advertise your new site.
The only thing I think Blizz should do to help players that do not wish to experience new content is to have the option to disable experience gain after level 59.
