I asked a question regarding forum software that matches particular parameters over here: Which free PHP based forum is the easiest to extend or customize?
This question might even be useful for future members when they run into the exact same scenario.
But my question was closed as an exact duplicate of: Which Content Management System (CMS)/Wiki should I use? - which it is not.
Can the respected moderators please consider re-opening my question and putting it back on the front page so it gets some attention?
