That would actually be a different function altogether. But not a bad idea! If you were to compare available voters to actual votes and they exceeded the requirement (set during the poll creation) of 51 percent (as an example) then it could state "Vote Valid".

Then after the vote was completed and audited based upon the two lists (available voters and actual voters) the poll creator could stamp the poll (vote) "Vote Confirmed".

So the steps would be:

Poll Creator:
1. Adds poll, sets validity level (percentage required to make the vote valid), selects output format (votes, percent or both), selects a specific group for voting (or no group, or a group of groups) and selects a time frame for the vote (midnight the 1st through midnight the 2nd as an example).
2. Notification is sent out to members of selected groups with a link to the poll and a time frame under which the vote applies.

Voter:
1. Voter places their vote

Poll Creator:
3. Vote Closes and notice is placed on the poll "Voting Closed"
4. Votes are compared to available voters and if a threshold was set and reached a notice is placed on the poll "Vote Valid". Of the threshold was not met a notice is placed on the poll "Vote Invalid".
5. Vote audit ensues comparing the actual voter list to the available voter list. If audit is clean then a notice is placed on the poll "Vote Confirmed" of audit reveals an issue the a notice is placed on the poll of "Vote Not Confirmed".

Did that make sense?

With this kind of mod I guess it would be "Poll Plugin Corporate" or "Poll Plugin Professional"
