Wordpress Email Subscribe Plugin (Daily Digest/Instant Notification)

This should be a easy project for someone who knows wordpress plugins very well. To explain what I want, check out this site: [login to view URL] So simply, they input there email and name, and select if they a daily email of all new posts, or instant post notification, and save. The 'Optional: only send me instant notifications if the post title includes one of these words:' **IS NOT NEEDED!** There has to be a way to unsubscribe, either by hitting save settings again without having the checkboxs selected for daily digest or instant notifications, or in the emails, an unsub link. You can use any of the plugins at [login to view URL] already. This is most likely why this project won't take long, as you CAN use another created plugin! Many plugins already have a instant notification email subscriber system, but lacks the daily digest. I want BOTH. **The emails must be sent in HTML** so that the pictures are sent too. Many plugins already have this though! **This has to be completed on or before Saturday!** Need this ASAP!
