@Southern Comfort - I'm curious why the last three matchups that you've started all have a closing date on the polls?
By default, this option is left open and unless there is a contest, timed tournament, etc going on, there typically isn't a reason to click that option. If you just leave it unchecked, the poll stays open from now until the end of time, or until the site shuts down, whichever happens first.
Again, unless you are planning on doing something with the results in a later thread or poll, in which case, never mind me.
