A non-profit org is putting up a forum for its 2,000 members. Would anyone care to share their experience with any of the following three forum platforms? I know there's plenty others out there, better ones, worse ones. For reasons beyond what I can go into, these three are being considered.
- phpBB
- Simple Machines Forum
- Vanilla Forum
Pro's? Con's?
Things being considered would personal preferences to flexibility, features, support, themes / skins,
SEO friendliness, or anything else you'd like to add.
Thanks!
