I apologize, I am the owner of the group and my computer has been broken for over a year, my admins haven't really been moderating the group at all, so I'm the only one working, and I had no way to approve join requests as I had no technology with which to do so. The requests expire over time, so it's my fault for not responding in time. If you still wish to join I will approve you right away. If not, I fully understand.
