The other day, Bornakk announced some good news that I think a lot of those individuals may have missed: They've temporarily removed the requirement to use an authenticator for the forums and the Armory. In the future, they'll be making this feature optional. You'll be able to choose whether or not you want to use the authenticator on the forums. Why would you want to do that? Well, if your account uses an authenticator, it's going to keep keyloggers and hackers/scammers from stealing your account or characters, but if the authenticator isn't attached to your account on the forums, it can still be used for spamming keylogger links since all that's needed there is your password. If you have your authenticator turned off, it's going to do a whole load of nothing to stop that from happening.
It's nice that it will be optional, but if you frequent the WoW forums and don't plan on using your authenticator there, keep in mind that you'll still want to be very careful about where you surf and what you click if forum access is something you enjoy having. In my experience, the forum mods are much less forgiving and not nearly as quick to respond as the in-game GM team.
