Hey everyone, Chat is here!
The chat can be opened with that little icon you can see in the right bottom corner of the screen, above the newly designed footer.
There are chat rooms for each country - and you will automatically be placed in the room for the country you are currently editing. You can see who is currently online, and see where they're editing - just click their name to focus your center of the screen to theirs.
If you just want to quietly move nodes around in privacy you can always go invisible, but what's the fun in that?
There are some thing we still need to work on - ranks displaying incorrectly, etc.
Please let us know if you see any issues at all! I'll be happy to answer all of your questions.
