Ragnorak: The most I would do is make it so that for one hour each day the inbox becomes unavailable. But thinking about that gives me a much better idea. Remember, the sun is more effective than the wind at making a man take off his coat.
How about if for one hour each day, each member shall receive 100 pluses for every minute they spend in the Green Room? So for the full 60 minutes that would be 6,000 pluses. The pluses can come from the billions in my account (generously gifted from Jacki) to keep the economy under control.
This way, even newbies could earn enough to buy lottery tickets.
