Today, V2 just announced the MR3 Preview Server will be live SOON.
The Access Codes
You will need an access code to enter the server like a password. Access codes will have a limit on how many people will be able to use it. They will be released by rounds so if you don't get to join the server with the last code from the thread then just wait for a new one.
Where To Get Access Codes?
Access codes will be posted in the Backyard Buzz section in the BYM Forums. The thread would be titled somewhat like "Preview Server for the New Wold Map Launches: Get Your Codes Now!" and will be stickies. Codes will be randomly sent to BYM players in their e-mail accounts so if you have no luck with the access codes in the forums then just check your e-mail.
Gameplay
Remember that BYM Preview will be a different application in FB. What you do there won't affect your main yard in the live version of the game. So feel free to experiment with the new mechanics.
Conclusion
Again, it's only confirmed and will start soon so just regularly check the forums for the forum codes. Complete MR3 Information is here. And here's some information about BYM Preview. Sorry for no new posts guys but I'll try to pull in more guides before I put up another ton of MR3 information when I get to try MR3 in the preview server.
UPDATE:
We already got to test the preview server.
