As a suggestion, it might be simpler to do your list in the order of the characters either joining or first appearing (in published stories), in which case it should have started with
* Kid Flash
* Aqualad
* Robin
* Wonder Girl
* Speedy
Also, instead of an "Other" option, you probably would have been better off specifying "Beast Boy / Changeling", the only member of "
Titans West" I don't see on your list.
By allowing an "Other" option, you can easily have people choosing that and complaining you didn't include people like Starfire, Cyborg, or Raven. Yeah, they didn't join until
AFTER 1978, but that doesn't mean people will actually READ your title / initial post before voting! (I had that happen several times in the JSA polls.)
A couple of minor nit-picks:
* Lilith wasn't "Omen" until many years later
* Joker's Daughter (Duela Dent) later changed her identity to "Harlequin"
* Bette was "Bat-Girl" with a hyphen (and was later retconned to"Flamebird"
post-CoIE)
Anyway, good luck with all of this!
