Yeah we have some fairly unique things here, it does take a bit of getting used to.
Easiest way to explain things is this
Forum sections here, click into one and you see all of the topics by default arranged, by last post. I am pretty sure you can organise them other ways in the settings, but I never see the need to do it.
Then my favourite feature of this site
Activity wall, where all activity on the site is collected. This is perfect for me as the head mod to check out everything and just in general keep up with things. Not to mention you can see people’s activity updates.
Other than that it works like most other forums, though the twitter-esque reply system is another feature I don’t see on many other forums. Makes for a less cluttered forum with less of a need to quote every post just to reply.
Just let me know if you need any help
