I bet a poll would work better. I tried to post my answer I got:
"We had a problem processing your entry:
There are already 1 messages in the database with the same subject line and body. Perhaps you already posted this? Here are the messages:
2002-02-22 12:02:17-05 by C. R. Oldham (cro@nca.asu.edu)
If you are sure that you also want to post this message, then back up and change at least one character in the subject or message area, then resubmit.
So I choose 4.5
