I am a started a forum for an employee group, our feature needs are:
1. Private – Threads will not show up in google searches.
2. Email – through forum and push from thread responsises.
3. Adaptable - iphone/android devices.
4. Secure – Users restricted to set IP or at least domains.
5. Cost – free
6. User friendly – Half of user base never used a forum before.
7. Admin Friendly – Although I have some programming experience I am not IT by trade.
Feature wants, but not required as I could click though to secure offsites.
1. Polls - anonymous and public (user votes displayed to group).
2. Document hosting – 100MB
I would say IP.Board?
FSR Admin - Vote for 2012.
