I am intimately involved in the organization of a relatively high-profile conference. It's a special situation -- I don't want to get into it -- and we have essentially zero admin support. The conference will happen relatively soon; most things are set, but I would feel better to have some organizational structure to lean on. Can anyone share a conference-organizing checklist?
Edit: I just reread this, and I'm concerned that I have to do more to convince MO that I am not a troll; I am merely posting from a new account to avoid identifying myself. Here's an attempt: I am an early mid-career mathematician, and when I ask all the more-senior people around me who I know have organized lots of conferences, they don't have a lot to offer, as they have always done it with lots of administrative support. At the same time, I know that occasionally conferences, even big ones, are organized "by hand" --- but the people who know the most about the details are not usually the high-profile mathematicians who organize a lot of conferences. This post is addressed those unsung heroes, so to speak. It is an earnest plea. Details on visas and poster sessions welcome.
