Hi Rowan, hope you are your family are doing well.
I got the impression that you are in the group hosting this site right? I'm thinking to make an AoH page on facebook that is global where events, invitation etc can be posted. There are a lot of local groups, but no shared page for AoH in general. If you and others wants to be admins on the site, just get a hold of me :) I'm on facebook quite a lot because I am behind a couple of sites, so it would be easy for me to share relevant AoH news through FB too.
