What Forum Software should I use?
I run my system on a linux machine. Let's say I use apache or cherokee webserver, for simplicity. I want to run a bulletin board software for discussion purposes. However I do not want traditional systems like vBulletin or vanilla, as systems based on these tend towards too much bickering and clique-formation.
I was inspired by the system in meta.stackoverflow in which each post can be voted up or down. This would instantly be a medicine for all the jerks, since their posts will get downvoted quickly. Moreover honest criticisms will get upvoted. So I feel this will be a great improvement. However the meta.stackoverflow system is not suitable for a discussion environment. I would want a traditional bulletin board system itself; but with the added capability that votes can be given up/down for each post, and for each post the number of votes is displayed.
For example let me mention that in some wordpress blogs, comments can be voted up/down. That capability is exactly what I want; it is just that I need it in a bulletin board software rather than in a wordpress blog.
Question:
Does there exist a bulletin board software with voting capability for each post?
Here I must stress that I do not care about the total reputation of a user. That is something I do not want to encourage.
I have asked this question both here and at serverfault, since it was not clear where should this be asked. Feel free to close it at the appropriate site and I need answers only from one place.
