It sounds good, I'm looking forward to it. What's the underlying platform, vBulletin, xenforo, or another?
One thing to keep an eye on. "the feature that we can "thumbs-up" (similar to "Like") forum posts" I'm on two other forums with "likes". In one case it has no real impact other than making the place a bit more friendly and interactive. In the other, it is both great and very controversial, because the combination of post counts and likes is linked to "status" levels. That does encourage much more participation, and people develop a lot of friendships and a sense of community. However, a small percentage of people (very small percentage, but it is noticeable and has an impact) get obsessed and do massive post runs (mostly in the joke/game or random ramblings type of sections) just to achieve high counts.
That forum also has a very nice feature, "alerts" where you get a little link on the menu bar to show you alerts- you can select what alerts you want, but main ones are when you receive "likes" or, much more important, when someone quotes you. The later is great, because if you post in a thread that you haven't subscribed to, you know right away if someone answers you directly or comments on what you wrote, and you can click the alert and go straight to that post. It helps keep discussions fresh and on track.
