there is no revenue from scrimmages right now... so it can't be split.
we are working on a newbie tutorial.. we hope to get some real users involved in it though.
adding a sponsor... as with most decisions i break this down into parts. one is realism, the second is gameplay. From a game play point of view, this would essentially just put more money into the economy. I think we already have a lot of mechanims for controlling how much money is availabe so that doesn't sound like much of a benefit. From a gameplay perspective i'm not sure how sponsorships would make the gameplay really that much more interesting or fun... just a little more realistic.
