Simple Solution -
Put it on your To-Do List - which is already organized by context (@Computer, @Phone, etc...) but assign a Due Date to it, and then set your Preferences in your Palm to show "Only Due Items."
If it makes you feel more comfortable - schedule the "Due Date" for one day before it is due (or two, I guess if you need the time).
Example: I have all my regular Monthly Bills set up this way - as repeating To Do's (which you can do in Outlook or the Mac Version of Palm Desktop)
Real-Life Example: Under my "@Errands" category - I have the following: "@Post-A.T.&T. (due on the 4th)"
It is due to AT&T on the 4th of every month - and it is set to "repeat" on my Palm on the 28th day of every month - apx one week before it is due to AT & T. "@Post" is my own shorthand - meaning "At Post Office." When I do a daily scan of my To-Do list, and this pops up on the 28th - I know I had better cut the check (which I can do anywhere, since I have my checkbook and "5 Travelling Folders" with me) and I had better run to the Post Office with it.
PS: If I have time (and money, lol) to pay a bunch of bills, I can change the view on the Palm so it shows everything - and then I can go through and pay them ahead of schedule.
2 last important tid-bits:
Using this system - when you HotSynch - the completed task is replaced with the next occurrence of the task (in my case - the one due on the 28th of next month)
If you have somthing that you want to show up on your To-Do List all the time, setting your preferences this way, simply DON'T assign a due date to it. Those show up all the time.
Hope this helps...
