Hey Andrew,
I just noticed there is no user ID in the chatlog and the logs seem to be aggressively pruned. So, I am not sure that the chatlog is the ideal place for a "moves" database. I agree that the chatlog needs to be pruned, so I think it might be best to log the moves in the game_board_game table along with their cvs buddies
The alternative to not prune the chatlog and fix the bug/issue with no userID being correctly logged in the chatlog dB seems to make the alternative of simply using the board_game_log more attractive and efficient.
