2: the number (as a majority) of officers or members of a body that when duly assembled is legally competent to transact business
EXAMPLE: The town’s charter states that a quorum of at least nine members must be present before any voting by the town council can take place.
DID YOU KNOW? In Latin, "quorum" means "of whom," which is itself the genitive plural of "qui," meaning "who." At one time, Latin "quorum" was used in the wording of the commission issued to justices of the peace in England. In English, "quorum" initially referred to the number of justices of the peace who had to be present to constitute a legally sufficient bench. That sense is now rare, but it's not surprising that "quorum" has come to mean both "a select group" and "the minimum people required in order to conduct business."
This seems like a good rebate with school starting; Buy $20.00 of 3M Post-it permanent or removable labels and get $10.00 back by mail. Your products must be purchased before 12/31/2010 and received by 2/28/2011. You need the original cash register receipt or invoice together with the original UPC codes from the Post-it package(s) mailed in with the rebate form. Although not specifically stated I believe it is fine to have multiple receipts that total up to $20.00 or more. Only one rebate allowed per household.
