Well, maybe not “lots of e-mails,” but you will likely get e-mails as people join your group. Here’s what they see when they join:
When you click on the “Please notify the group manager” link, it opens an e-mail with your e-mail client (one of my pet peeves on the Internet) and this subject:
I would like to join your group; my membership is pending approval
Just so you know, when I get that, I go in and approve the request (no more than once a day, I wish it could be once a week), and then reply back to say “okay!” or something simple like that.
