User #16 here.
Great concept! I really like the invest idea. I might have missed this but I don't see any place to dynamically see what my investment is worth. For example, it would be good to know how much I'll make if I withdraw my share now.
Also, can you clarify "Commission is charged when profits are divested, or at the end of each week, whichever happens sooner"? How would you handle a loss scenario if the end of the week is reached and overall, my investment is in a loss.

The 'invest' tab shows you what your investment is worth right now, and what percentage of the total bankroll you own.
The 'stats' tab also shows you your investment's value (it changes constantly as people play).
I'll write a more detailed description of how the commission works when I get a chance. But it's as fair as I could make it. You only pay on net profits, and only on profits above the level you've previously paid commission on. If you're at a net loss by the end of the week, you pay no commission. It seems rude to charge you for losing...
