MonopolyCityStreets has two forms of active communication.
1) blog.monopolycitystreets.com
2) Twitter: @monopolycitysts

Many users in game are complaining that there is incorrect tagging, naming, and location data. MonopolyCityStreets is blaming all of these problems on OSM.

May I suggest that we create a special landing page or highly visible link for new users coming from MCS that briefly explains the project, that emphasizes the data is constantly being edited, an estimation (or even exact date) of what the basis for MCS street data is, and how they can help contribute.

While a few pages like that exist currently, it might be helpful to have one specific to MCS. It would also give an idea how many people are coming to OSM from MCS.
