As mentioned earlier, groups.io provides some additional features which we could consolidate, eg. Wiki, File Repository, Polls, Light Database, Chat, etc.  With one place to go to connect to them.  For those who want everything in email, including limiting your received email to plain text.

A couple of features I like are sub-groups (we can have multiple sub-groups for things like VPN, 44-Net, Grants, HAMNET, Hamwan, etc. or regional/language specific) so people can focus their discussions and you can setup both social login (Google/Facebook) and a list of email addresses that you can send from (e.g. k7ve@k7ve.org and john.hays@ardc.net for me).
