Tournaments and Omnipong
I've run over 120 USATT tournaments, ranging from monthly tournaments at MDTTC all through the 1990s to the 1998 Eastern Open which received 411 entries, still the record for a four-star tournament. (Richard Lee was tournament president for that one, his first big tournament, and he's been running them all over the country ever since with North American Table Tennis.) Running a large one is a massive undertaking, and even the smaller ones take far more time and work than most realize.
I sometimes think all tournament players should be required to run a USATT tournament just one time, to see what really goes on. Observant players have a good idea of what tournament directors do during a tournament; really observant ones who think it through have a good idea of all the work that went on before the tournament. Before the tournament, directors (sometimes working with a referee) receive the entries, enter them onto the computer (unless, heaven forbid in this day and age, they are running it by hand, on paper!), check all the memberships, create draws (including checking for geographical separation and other complexities), finalize the scheduling, and print everything out so it's ready. They get all the tables, nets, and barriers in place, put up the table numbers, and make sure everything is clean. And then there are those thousand small details that, if I listed them all, it'd take up about a year's worth of blogs.
There's also the more advance work - scheduling the tournaments, creating the entry forms, circulating them, publicizing the tournament, and so on. I change my mind; even running a small one is a massive undertaking!!! There's a reason why "tournament" is just an anagram for "one tantrum."
