Just a note about the LOTRO beta, you need an active subscription (as in paying) to be in it, otherwise you only get a two week trial. If you already have an account but it has expired you need to pay a subscription again to get into the beta, otherwise you need to set up a new empty account which then goes back to the trial period mentioned already.
