I just searched for this and couldn't find an answer (maybe would be clever to put this info on the "Subscribe" info page ). I checked my profile and there was no info there either (like: "subscriber since" or "subscription ends:").
I bought a subscription about a year ago. It's bound to end any minute now. Will I receive a "please renew" PM? It's not a big deal, but I'd rather not get bumped out of subscriber status and have to newly re-subscribe. How do I buy a new subscription to start when the old one ends (ie not immediately but as a renewal?).
