It's an odd one.
One of the great things about B&C is that everyone is able to engage - they can share opinions and gossip with one another about how cool x or y miniatures are, what they don't like about a recent business practice or why they think an alternative decision might have been a better course of action and so forth. Unfortunately, there's a fairly consistent group users who go out of their way to derail threads - insulting other members, intentionally steering the topic into off-topic territory with irrelevant discourse, joining a thread to snipe at a specific army or part of the business that really isn't relevant to the discussion and so forth.
It can lead to a lack of faith in the moderators when a thread is fragged because the usual suspects have come in, derailed it, and as far as can be seen gotten off scott free - and that's including the stuff that goes beyond the norm, i.e. the sexist remarks or disparaging remarks or phrases relating to disabilities that some users seem to think make for appropriate discourse. I don't know if it's simply turning a blind eye to long term members / friends or if it's simply a lack of reporting going on but it's very not right.
I feel people might be a bit more confident in the staff if repeat offenders were more visibly reprimanded in front of the forum for their behaviour - be it a more visible "probation" tag to replace + FRATER + whatever, an enforced avatar change, etc. It's much more fair than fragging a thread because of a few bad apples, and with a little luck the public shaming will kick them back into line.
That's pretty much my two cents. General thread moderation can be a bit harsh at times, although that's strictly related to other poor behaviour - and I must admit, I'm not a fan of splitting the conversations off into the sub-forums until post-release, but then again I'm also much more in favour of trying to condense / control the number of threads a bit better.
As far as third-party content goes - I don't see why it can't be in News. We're a hobby forum last I checked - we're all about the different things to expand and improve upon the systems that this forum covers, i.e. those relating to the Warhammer 40,000 Universe. It'd be an utter betrayal to our community to frag and disallow it. I suppose the only other alternative would to be to split News into first and third-party sub-forums, but that just creates extra work.
