If anyone has been thinking of multi-boxing a different game, EQ2 has just come out with a recruit-a-friend much like the one WoW has. Details @ the link.

Personally, I find this highly amusing as my husband and I restred our old accounts there the other day. not more than 4 hours after we patch up and first log in, as we're deciding if I can manage to multi-box the game, they post the RAF news. It's fate.

Edit - And yes, you can use it to box Per a ticket I submitted last night :

For the new Recruit a Friend promotion, yes you can use it to invite several of your own accounts. We specifically set the rules so that this would work and be attractive to many of our customers. As you noticed, this promotion can result in a substantial amount of free time. CSR Xavier "Spadaccino" M.
