Technically membership does not expire -- though launchpad membership has an expiration date -- all one has to do is renew their membership. In this case it expired while dmizer was away. The normal process should this happen is to write the membership board that your membership was approved by.
+1 good luck
Power tends to corrupt, and absolute power corrupts absolutely. Great men are almost always bad men, even when they exercise influence and not authority
It's now a bit after-the-fact (congrats, BTW), but I think you just want to see how many ways you can be approved for membership.
I shall remain grateful for your help in getting my membership a few years ago.
