It's actually going to be held on jw.org, a live stream, each weekend for certain districts (or so they are told)
On the left and right of the page there will be donation box graphics where if you click on it, you can use any credit card, paypal, etc to make a donation and have a tax deduction receipt printed.
On the top and bottom borders of the live stream will be continuous scrolling spiritual slogans, "Trust in the FDS", "Obey the elders", "Give more and be blessed!" etc.
At the end of the 3 days of the spiritual buffet, the speaker will be sure to mention in a falsified report, "Expenses for this wonderful spirtual food this weekend have amounted to $400,483. Donations received are $20,473. (in a pathetic pitiful voice) Thank you for your support with Jehovah's program" - thereby guilting everyone to give more or donate again.
