Maybe the easiest way to keep in touch with us is by using emails. We have a mailing list where developers and community members hang out. If you want to subscribe, send an empty email to firstname.lastname@example.org. You can easily unsubscribe when you want.
If you prefer a chat, you can find developers and community members in the channel #yorg on freenode.net. If you don't have an IRC client, you can use their web client. Please note that we can't always answer promptly: it may take hours to get an answer (but we answer always), please be patient! :)
If you prefer social networks, we are also there (links are in the side menu).
You can also reach us in the following communities:
