I'm still waiting on mine, but I've been doing these for a minute now with the vault, they do about three a year and there's no drop time requirements of when to drop usually. They do require that when you drop you do once a week MINIMAL updates in this thread, although you may start a thread of your own as well. Failure to follow three above rule can/will disqualify you from any further vault promotions. There's usually a moderator that oversees this thread until the end and makes a list of the people who actually participated and the ones who did not. They are cool about the timeline and understand some of us can drop right away, some of need to clear some shade for legal purposes. Their main goal is the documentation this thread. Hope this explains it well.... Also if you can only drop one at a time that's ok too, just try to remember to document all of them here. Hope this helps
