Mock stock market challenge

There has been some interest in starting a stock market challenge over at Marketwatch. Of course, everyone who is interested in playing is welcome to join.

We do need to set some rules:

Starting cash amount [$100,000]:
Public portfolios [y]:
Portfolio resets [n]:

and then if we're going to allow any advanced options (margin, shorts, stop loss orders, etc.). I think the defaults are fine and the advanced options are fine as well, but I'm open to suggestions.

Edit:

Game ID: swordscrossed
Game Name: Swords Crossed
Password: bernankerulez

The game starts on the 24th and ends on 3/25/09 -- the day I turn 25. Try to be signed up by the start. Everything was the default options as far as rules are concerned. Best of luck to everyone!
