In terms of brought up issue, I personally do not see a reason for another website. Just because dates will be clearly labeled doesnt mean people won't create games on the same day..
We could have just standarized game names in ASC to clearly state when they are happening. For example <Date> :: <Location> :: <Name>
May 12 :: Finch Field :: Skirmish Game
May 11-13 :: Muskoka :: Force on Force Patrolling Exercise
Besides larger player base, some hosts are not doing it "full time" or with profit in mind. So they do not have luxury of choosing dates. Whenever a field opens up or they have personal time to host thats when the game can happen..
