Michael: As I recall, this was made more-or-less clear in some additional wording that appeared on the same screen as the "View results (null vote)" button.
Rich: I don't remember anything explaining that I would forfeit my vote by looking at the results first however, so either I spaced on that information or it was not clear.
JIM: I also don't recall seeing anything of the sort. But I didn't try to view the results first, since I had just created the poll and knew there was nothing to view.
Now I can see the results above all the posts on this topic. Is that not visible to those who haven't voted, yet?
So we know we're missing at least two entries in the 13-or-more category. (For Rich I should have 100-or-more

)
