Randomly select a winner or winners from the comments of a giveaway post.
The plugin uses MySQL's RAND() function to pick the winners directly from the database.
The more comments your post has, the longer it will take to parse the data and determine a winner. Also, if you choose to "Discard multiple entries, but allow the entrant a single entry" the plugin has to do an additional database query to get your results, which takes more time. Be patient and your results will be returned as soon as possible.
It may seem counterintuitive, but if you re-run the plugin on the same post and occasionally get the same winner, this proves that the plugin actually is random. For example, if you roll a dice several times you will eventually get the same number twice in a row. The same thing happens with the plugin. However, if you run the plugin several times in a row and keep getting the same winner, that could indicate a problem.
