Hi Lawrence,
The first thing you need to know is where the expedition is headed. You can get all that info from this post :

To bring you up to speed, the expedition is currently heading to Waypoint 2 in the Omega Nebula, where there will be a week long mining community goal to help build a new space-station at the galactic core. If the CG interests you, more info on that is here:

The fleet won't leave the Omega Nebula until Jan 27th - that's when WP3 will be announced on the first link I posted above.
Fleetcomm PG is closed as is the FC server for the time being due to massive backlogs, but if you don't want to do DW2 in open play, check out Mobius group:

For in-game chat with fellow explorers consider joining one of the Squads that still have spaces open (EDSM and DW3S). You can find them in-game, via the right hand panel, squads, search squads. This is a good chat-substitute for discord servers if those aren't available.
You can follow updates on Twitter :

The DW2 website contains links to everything DW2-related :

The basic premise of the expedition is to follow the route and submit your discoveries (if you want to) to this thread:

Travel at your own pace (avg. 2 hours per week is needed though), make friends along the way, and at basecamps learn about the projects and events to take part it - that's the basis of the social aspects of these kinds of events, but you're quite welcome to do DW2 alone or with a wing-mate.. its entirely up to you how you want to experience it.
I'd recommend you read up about as much of the expedition as you can if you're late to the show - its a long journey, 18 weeks just for the outbound trip, so its something you need to be sure that's for you.
Fly safe o7!
