This plugin randomly selects a winner or winners from the comments of a giveaway post. It only lists the 100 most recent posts to reduce strain on your server. You can disqualify people who’ve entered more than once (determined by email), or reduce their entries to only one. The plugin uses MySQL’s random function RAND() to randomly select the winners directly from the database.
此外掛程式已可供下載，並可用於你的 WordPress 自助託管安裝。
