I agree, and that's why I got rid of it all with the exception of the three which I'll allow. All posts default to the lightbulb and since only Moderators or Administrators can create polls on my board, they're the only ones who can use the Poll icon. The sticky icon only gets used if they know a post they're creating is going to get pinned. Otherwise it ends up defaulting to the lightbulb as well (i.e. if they pin someone else's post). Not the perfect solution, but it's the best I can do for right now.
I really would like to get this functional though, so I'll start working on it. My custom image hack will have to take a back-burner.
