Affiliates who want to take advantage of the event should contact the site for tools and linking codes based on the site's CCBill-powered affiliate program.
According to Mark Prince, site founder, the reasons for the change were chat hostess availability.
"Our site, and much of our network, is made of real, girl-next-door college students and amateurs, and April 7th was too close to finals for them," Prince said.
The site launched a first Girl-A-Thong party last year in May to pay thanks to regulars who had stuck with the site.
Although basically a free four-hour drinking game party featuring up to a couple dozen cam girls on double-stream video display, the site makes sales by allowing the free users to click a link to buy the girls rounds.
The webcast event features two simultaneous live streams at approximately 150kb/s to 200kb/s each.
"We could stream at a higher rate," said Prince. "But we found that some users simply can't sustain a download of more than 400kb/s due to either slower connections or slower machines.”
Girl-A-Thong III begins between 8:00pm and 9:00 pm EST, Friday, March 31.
