First, thanks for taking the initiative to start a group with us.  We admire everyone who takes the initiative to start a group and want to make sure you have a great experience.

Posterous Groups is a pretty new service, and we have lots more functionality to add.  We'll be using this group to get your feedback on what we  what we do next, but its main purpose is to provide tips and examples for other group admins.   If you need to report a bug, we'd prefer that you sent it in to help@posterous.com as you will get a much faster reply.
