I finally was invited to participate in "missions."  I read all your discussions about it and was kinda sad not to be part of the club.  I may never be able to be paid next to nothing for 1000s of photos of bananas.  Now that I'm included though, wondering if its worth it?  I have the opportunity to photo people and an empty space for $1 for the pair of photos. 

Are you all participating? How long is the review process?  Is it one mission per quarter or more/less?

I was wondering the same thing.  I'm not sure if I was nominated for other missions - am not great at keeping up with e-mail these days - but received the current one and it seems easy.  If it was ten bucks a submission so I could make a quick $200 I would do it but for a buck each and a max of $20 would only do it out of curiosity.  Since there is no keywording and the same model could be used I could be my own model and shoot them in 20 minutes, processing would be minimal to just change the file names and upload.  Might take 40 minutes to an hour in total but that isn't really worth $20.  Unless it would get you into other ones that maybe pay more.  If anybody has done these, do they sometimes pay more than $1 per entry?
