Please be aware of any kind of promotion sent to you from anyone other than the Mathematics Meetings Service Bureau (MMSB). There are no other 2020 JMM websites other than this one.There is NO other company or organization authorized to reserve rooms for you, register you, sell you booth space, sell lists, or the like. And there are no promotion codes generated with special deals. All JMM rates offered at the official JMM hotels are already heavily discounted solely for this meeting. (See jointmathematicsmeetings.org/meetings/national/jmm2020/2245_hotelpage for a list of all official JMM hotels along with rates.)
These groups are getting more and cleverer with their promotional campaigns, including using our pictures and logo, mimicking our website, and even listing themselves as representatives of the AMS and MAA; nevertheless, they are SCAMS. All correspondences from us will come from firstname.lastname@example.org ONLY.
