I'm in the process of implementing my GTD process, and I'm starting to run in to items that I want to put in a tickler file. The implementation of a physical tickler file makes tons of sense, but its unwieldy for me to have a physical tickler file. I'm trying to set everything up using remember the milk, but I'm willing to lean on other tools to complete the task. I've taken a brief look at the "Tickler file for email" question, but I was wondering what other alternatives people would recommend, or have had success with, in particular, using remember the milk?
I realize that StackExchange is not the place to ask for recommendations, but I'm at a loss: What does a digital tickler file look like, and what tools / techniques can people recommend?
