I love this idea! Get email reminders by emailing to an address with the time period to want. If you need more time you can postpone with a single click. You can also sync to your Google Calendar. Reminder service is free, but more 'paid for' features are available.

Student version of Kindle is confirmed for students. Oh so cool. My students really like the idea of a Kindle and I'm wanting to get a hold of one. They will HAVE to make it easier to add all blogs to the information on a Kindle -- I'll want their Google calendar and my class blog to download automatically. It is too hard to add info to the Kindle now unless you publish a book, and then it is easier. Need an ebook of some kind.
A superb Apple and Android app from IFTTT which lets you setup one click notes which can be used for many online services. You can send a note to your email, add something to Evernote, or even add something to your Google Calendar by extracting the details from the text. Use it in your ongoing assessment by quickly noting things you notice in class.
