Send a message to someone in the group that has been more active than the leader (who hasn't surfaced since December). There are 4 that signed into waymarking.com for today.
Ask them to double check on your submissions. Your submission may have gone to Group Vote and were declined. Sometimes the reject letter gets lost in the mail.
The four that signed in today are also active in many other groups, too. So they may have missed them with all the other submissions they receive.
I'm in the same boat, I've got one still lingering after it was originally denied (wrongly, in my opinion). The re-sub hasn't been looked at for a month despite promptings.
