I think there were some people doing that with whole seasons of 24, but it would take me a lot of coffee to be able to pull a whole day doing that. 15 hours falls into "I could do it, but I don't know whether I should" territory...
Aside from that, how did you like the show? Is it just a modernized/revamped version of ER or is there something else to it?
Anyone here using it? I am not sure I understand their pricing model. Is it just "the more users you have, the more likely you are making money from this and therefore the more you can afford?"
