Glad to hear it's working

As for the 1 month deal, I usually go that route (buy a month, and don't continue unless there aren't many admins active (Curse you Diablo 3 >.>, stealing our admins...)).

But yeah, what I do is the following:

1) Buy admin on the IBIS site with a CC.
2) Once admin is working, go back to paypal account and deactivate your CC (I use it only for 1-time payments).
3) When the time to renew comes up, it will send you a notification in your email (Transaction canceled) or something because you have no money in the account and the CC is no longer tied to it.

There are a couple ways to approach the issue though (Michelle's seems more the "intended" way though haha), but hope it helps
