Use Simpleology to remind me when I haven't received a reply
Since you can send things to the DreamCatcher via email, you could use it a reminder when you email someone and you want to make sure you'll remember to ping them if they haven't replied yet.
Just add DreamCatcher@simpleology.com to the BCC in the email, and the subject line would be added to the list. Then when you go over the items during your Start Your Day, schedule that item to when you want to receive the response.
When you receive it, mark it as done! If the day arrived and you haven't received anything, you know to send a reminder (and you can find the email, cause you know what the subject line is!)
Cheers,
Itai
