Since running in coil, I have seen a number of problems and drama come up within FC's.

Do not lock players out of previous turns that they have completed, but DO lock them out of the loot pool for the week, so they may at least help other people get through or train them.

There are many people left out while groups are already filled.
There are people with off times, but because a number of people are locked out we cannot help them.
This suggestion would also help out many of the smaller FC's
