Post count based contest for posts between certain dates

[kh99]

I think I would create a new database table and copy over the userid, username, and posts fields from the existing user table, and then do the same at the end of the contest (or maybe the new table could contain a date field so you could use the same table for start and end). Then at the end of the contest you could find the winner with a query that calculated the difference. Or you could export the table to a spreadsheet if you're more comfortable with that.
