I think they are saying that when they do a group show, they "dance, work, undress doing everything" but then when the group goal is not met, they lose any pledges made so far.
Mikhail & Sergio,
While I think it's appropriate to tease your clients a little, show hints of what they might expect once the group show has begun, I don't think you are actually supposed to "... work, undress doing everything" until the group actually starts.
Showing and doing everything before the group goal is met well.. that leaves the member very little reason to pledge and complete the group. You already did the things they want to see before hand.
