forget huge list. my company has ~30 people, unfortunately most of them 
have names that begin (some names are changed to similar English names 
to simplify my example) with J (jim, john, josh), S (sam, scott, sharon) 
and T (terry, tim, tom). As such, using autocomplete works a lot better 
than the listbox (in fact there are usually ~5 people per letter and i 
usually want the middle one). As the list grows beyond 30 things get 
considerably worse, you get more collisions and you're always better 
served by any form of completion or nicknaming. Browsers especially 
mozilla tend to behave terribly with any form of a list like this.
