Thanks for that Austin, that's good to know - though, that's not
exactly what I was looking for. I do need everyone using their own
tables, as they'll be posting their own list of shows.
So, current behavior in terms of inserting data is fine - it's looking
for the tables that I *want* to be there. But since GigPress is
installed in 'mu-plugins', blog users never activate the plugin, so
their own set of tables never get installed.
I suppose I could do a quick 'SHOW tables LIKE' check on admin_init to
see if the tables are there, and if not, install them, but that seems
