I am surprised that the owner of the websites/companies that the sig campaigns were advertising for have not made any kind of announcement saying they will cover payouts as they are responsible for their participants getting paid at the end of the day.
I advised mexxer contacting the owner of e-coin to ensure that they step foreward and cover the payouts. I also commented in yahoos "I'm desperate, what to do" thread with a similar advise (which seems to have been burried under the other replies).
At the end of the day, this shouldn't been dealt with on costs of the participants.
