Because we have a large number of posters this year, we will have to use more than one type of poster board.

Posters # 1 - 24 will have mounting spaces 3 feet wide by 4 feet high . Posters 25 - 35 will have spaces 4 feet wide by 5.5 feet high . If you are in a smaller space, and desparately need the larger space, please let me know (jeilek at aoc.nrao.edu) as soon as possible.

(In case you're wondering, I grouped posters by approximate topic, and put the high numbers on the large boards because one author asked for that. Nothing more nefarious than that, folks ....)
