The IJM has a sample .tex file for an actual paper.  It is in  \documentclass{amsart}, which uses the command \subjclass{} for the msc numbers.  This makes the argument  appear in an unnumbered, unmarked footnote at the bottom of page 1.  So apparently that's the usual format'' for the subject classification numbers.

I have tried \footnote{}, but that makes a numbered footnote.  I have also tried \thanks{} within \title{} or \author{}.  That also puts a footnote where I want it, but marks it (and the title or author's name) with an asterisk.  So how do I get an unmarked, unnumbered footnote for the msc numbers at the bottom of page 1?

Make a file w/ the \documentclass{amsart} format and use the command \show\subjclass to see what it is. Continue backtracking as necessary until you arrive at the original definition (or just look through the source for amsart and find it there).
