Hmm...if I forgot to point it out, stating your event SED was meant to be ENCOURAGED for players looking to be HITTERS. It's meant to be optional by nature and not necessary for finders though if you feel like stating it too for any reason such as helping other players recognize you need help (no offense intended), then far be it for me to stop you.
But yeah, if you're signing up as a finder, you don't need to say your event SED. Hell, even if you're applying for hitter, you can opt to leave your SED blank, we'll take your word for it.
