Do you mean that when I hit "submit" there are duplicate entries submitted
or that it may match what someone else has submitted and become duplicate?

If it's the second case, wouldn't that be optimal? You'd know that X people
had the same issue/question and you can reply to each one when it's

Makeing the column unique is the easiest way. If you get a "duplicate" error
from mysql_error(), then just ignore it because the problem is apparently
accounted for.

No one does anything manually... :) Easiest way to "fix" your data now would
be to make a new table with UNIQUE columns where you need them. Then do an
INSERT INTO ... SELECT to move the data from one table to the other.
Duplicates will be ignored by the new table. Proceed as normal... :)

Do you need to "remember" anything that the user enters in the form that's
specific to that user? That's all cookies are... a variable that you store
on the user's machine. If you don't already have a reason for them, you
probably don't need them.
