I signed up - but it is a little confusing. It seems I can only earn with Turkish and not with the others - or at least there is no way for me to add any info for AC or UA.

Edit: it seems one must earn a minimum of 1000 and then I suppose they become eligible to transfer out to whatever program they want. I suppose I have to trust them enough to potentially waste my time writing 10 reviews and then perhaps not receiving anything.
