I have noticed if you go to your message board in the diversions tab that you get a copy of the moves that your opponent made each turn but so far that is it.
Positives:
- Adds a notification for each time it is your turn even if you don't see it in your personal email.
- Putting a number next to the Diversions tab doesn't impact the inbox.
- Encourage more players to play a round or 2 of chess while they wait for their turns to come up in their other games.
- Similar programing is already being used and would just need to be added in another location and modified.

Negatives:
- Fills up your inbox up quicker due to the 50 message limit (if the PM is used)
- Some players don't like PMs sent to their inbox so they might not like it (if the PM is used)
