So I've been researching forum solutions lately. It seems there's been a lot of discussion of this topic over the years, but it's kind of hard to get a good idea of where things stand now.
Here's the situation I'm in.
I'm setting up a trio of sites: A Drupal blog/news site, a related wiki, and a related forum, all on different domains. Drupal's forum and wiki capabilities were a bit lacking, so for prototyping I set up Mediawiki and phpbb.
Those two programs are really great for what they do, and if these were independent sites I would be happy with what I have. The problem is with integration. I've been trying to figure out how to integrate user login, themes, input methods (wiki format for everything), across all three sites. There are solutions, but they're a bit daunting. Going all Drupal obviously solves a lot of problems, but makes me face Drupal's limitations.
My real question now is what's easier: integrating phpbb, or adding features I need to Drupal's forums. There's a number of issues, some of which might not really be a problem, but just my ignorance. I'd like to know if there's a way to make Drupal behave the way I want, or how hard it might be to modify the forum module to work this way.
1) Threaded vs. Linear Discussions. I don't want threaded discussions on my site. I know they have some advantages, but I have other areas that work well with threads, and the forum I want to be strictly linear. Is there a way to set this just for the forum? The comments setting seems to apply to all comments. If I have a multi-site will it make this easier.
