We all sympathise, but repeatedly posting to a public list after a) one of the organisers has indicated that he is dealing with it and b) you've been asked to take it *off* the public list is unlikely to help.
If you haven't had a reply within a reasonable amount of time (I'd say at least 24 hours to account for time zone differences), then email the organisers (note: not the public list) again.
