Thanks. I expect my sessions to be longer (30 minutes?). And if I were only expecting hundreds of users, I wouldn't waste my time. I'm hoping to hit at least tens of thousands of registered paying users. I do expect to have portions of "grossly inefficient code" (much faster to implement in some cases) initially that I plan on solving (when they become the problem to solve). My product/site will be highly collaborative (I know, everyone thinks this, but, I think my idea is different (I know, everyone thinks... ())) and with a larger than normal communication component.
