My company has a “UX community” that has regular meetings to share and communicate progress. It’s useful, but a little “echo chamber-y” for my tastes. The key way to keep in touch is to be involved and engaged with the work itself whenever possible – getting the information second-hand isn’t nearly as useful as being “in the trenches” and seeing when something happens.
If this is not possible, then outreach to peers in your organization when you can and have casual touch points to grind out what is going on – you’ll learn more in my experience from a chat over a drink than you probably will through a formal set of meetings…
