The rumor-mill has been churning out rumors again. There have been rumors flying around that Facebook will soon charge a montly fee for access. These are nothing more than that, rumors. The rumor originated by certain emails or messages through Facebook that would tell users that Facebook would soon be charging for services and to sign a petition against it. The group that originally started the rumor seems to have been deleted so I cannot link you to it.
I faintly remember the same thing happening on Myspace before Facebook was around. The same thing happened, there was never a charge and it was all rumors. Just a reminder, before believing rumors contact the business first to confirm those rumors before spreading. Now, back to Farmville.
