maybe we can even ask the viewers to pick who is the 3 mods to
be kicked out every week. more fun!
the last one who survived will stay for 4 weeks from the days
he/she appointed.
At the end of 4 weeks, we nominated 3 new persons to be mods and
the game begins!... 
In this case, the mods will be trying his best to keep his job by
posting the best threads n stay active.
