Just another suggestion in order to make sure you do not miss a date - delayed email.

I process a lot of email every day - it is a part of my work. So, I am very confident that I will check email every day. I send myself reminders via email for tasks that start in the future. I think, Outlook has "send on a certain date" feature in an email.

If you check email frequently, send a note to your future self with a reminder to do whatever or check your dormant project. I do still review those in my weekly review, but it takes almost no time. I know that when time comes, I will get a knock on my door.
