Lock in forgiveness
Just an idea/suggestion to go with the new "must lock in or assumed afk" thing. Since it's really easy to forget to hit the button before the timer expires: forgive the first offense in a 24 hour period, at least while we get used to it.
This way, if you forget you can queue back up immediately. Limit it to 1 per 24 hours so that it can't be abused. Maybe also make a limit like 5 times total lifetime so that people who do remember don't get 1 free/day.
