In case you've not noticed it, there's a new icon sitting in the Add Content panel of your MIX. At the bottom, you'll see Notepad. If you add this to your MIX page, you'll get a handy space to jot down any reminders, to do lists or web addresses you want to keep hold of.
Highly useful if you're desperately trying to adhere to a paperless office policy. WebTwitcher feels your pain, as an ex-obsessive user of post-it notes.
