Board numbers

Dear conference organizers:

If you’re going to mount big numbers of poster boards in such a way that the poster presenters can’t easily move them around (like, say, stapling them to the board), make sure you tell your presenters the size of the board minus the size that the poster number takes up.

An actual poster board may be 48 by 72 inches. But if the board number is 4 by 8 inches, that effective working space for the poster maker is 44 by 66 inches.
