True, maybe they should though, :p. I just wonder if these other guys that are joining realize that until they're confirmed, they aren't confirmed. So people who joined a couple days ago may not be confirmed and may not even be accepted, despite going around to make posts.
I suppose it is reassuring to have official confirmation as soon as possible. That said, they stated there was no limit to the number of participants of this campaign, last I asked, and if people followed the enrollment "procedure" correctly, there is no realistic reason they shouldn't be accepted, even if confirmation takes longer.
Nobody has unlimited funds. A lot of times people also don't consider the long-term costs; they have estimates they go with. It's the same as when an ISP oversells because they *hope* that the demand will be less than a certain amount. I've seen other campaigns here go through the same issue; they set aside x amount and then realize how much they really need.
I really hope that doesn't happen here, but still, until each person is verified it's not a contract.
