The best way to get involved in the Codecademy community is to answer questions here in the forums and participate in the discussions we have here
Not only does helping out here on the forums help you learn the programming language better, but you can also get to know some of the “regulars” through private messages and such.
If you're looking for in-person meetups you can do, there's a list here: https://www.meetup.com/pro/Codecademy/. Unfortunately, it seems that most of those meetups have become inactive in the past year or so You might be able to get them revived by emailing the organizer, however.
I hope this helps you, please reply with any more questions you may have!
