- Login security - obviously parents would not want everybody knowing their kids' names & addresses.
- Event scheduling - another obvious one, since Scouts have lots of things going on - Pack meetings, campouts, etc.
- Messaging or announcements - something to help people communicate with each other, that could take the place of the Yahoo group emails.
- Roster - an authoritative list of members.
- Storage for files & photos.
By the way, lots of sites claim to have email lists, but to use them, you have to log into the website and send your email from a special page. Often, you have to be an administrator to be able to send an email. That's not an email list.
A true email list is when I can open gmail, type everybody@domain.com, and it goes to everybody I want it to. Also important: all members of the email list should be able to send emails to the list. Anyways, that's a great feature. That plus the Announcements feature effectively took the place of the Yahoo groups, and I was finally able to wean them off of that. Woohoo!
