What mods does this site use?
For the most part and what the average person has access too, it's a bare bones install of SMF 2.0. All the features you see should be available in any install of SMF 2.0 RC1 at the moment.
Other than a version of the topic solved mod.
Well that is to the best of my knowledge, but I'm sure a Project Manager will have better details.
Ah, okay :)
Topic Solved and a custom method for linking to topics (wiki style) are the two main ones, although there are a few other custom ones (integration with our CM helpdesk being one)
Our install of SMF is pretty close to the default. We don't try to add extra stuff because it would create the impression that such a thing is a default feature. It also would mean our updates would be dependent on specific mod authors. Considering we often run development editions here for testing, it wouldn't work well.
In terms of the actual modifications we have here, most are for team-specific functionality. They do things like tell us how long it is until the next team meeting, or how many tickets are waiting in the CM helpdesk. The only ones that would be visible to the public would be Topic Solved, Language-based board index (moving language-specific boards to the top, if not using English), auto-detection of a language to show (based on what the browser reports), wiki style links (which most users won't see anyway), and the integration with our customize site (for user accounts).
