I'm looking for a forum software which can run on a regular LAMP server (preferably). But the main requirement is that the end-users shouldn't need to register etc. Just let them login with an openID provider.
Don't get me wrong (the title says registration)
So a new user visits, wants to post, shouldn't need to register, just redirect to openID provider for authentication and allow to post. Basically common-sense usability which no forum provides currently (AFAIK). No registration, just login.
