The dust settles. Mana was exchanged. Closed-door conversations fall silent.

 is the 12th. The same Manifolder cannot be in the chain more than once.

A new Manifolder is added to the chain when the last Manifolder in the chain managrams another user with a memo that contains and starts with the phrase "double it and pass it on" (non-case sensitive). I may make good-faith exceptions to this memo rule at my discretion.

 double the mana they had received. Managrams made with what staff deems to be counterfeit mana or during a period the site rolls back through do not count. 

Additionally, their managram needs to be made within 48 hours, down to the second, of them receiving their initiating managram to count. 48:00:00 after counts. 48:00:01 does not.

Only the 1st valid managram sent by a user counts. Sending multiple to the same or different users will not count the 2nd attempt and beyond.

Market resolves to how many Manifolders successfully "doubled it and passed it on" with valid managrams. (This is not how many Manifolders are in the chain -- the starting seed doesn't count.) Only one market answer will resolve YES. The rest, NO.

Shame upon the Manifolder who breaks the chain. That, or shame may be brought upon the Manifolder who sends their managram payload to an inactive or distrustful user.
