Hello Jenny and welcome!
Thanks for setting up this group! I'm working with MA for the next few months to help establish the network and to assist in any issues members might have.
I wonder whether it might be useful to add some information about the group to the text box. Let me know if you need a hand with this!
Additionally, there is a way of automating invitations if you need some help with this too! I look forward to hearing about AusStage!
