I did something like this for a couple of years, although it was nothing more than a sheet of paper with a list of names. Then, towards the end of 2001, I compiled everyone from the past year onto a spreadsheet, and I included more details, such as what was done, etc.

I told this to a friend of mine, and he and I then tried to come up with a name for a computer program that could keep track of one’s sexual encounters.

There’s iTrick, as Brad points out in Mike’s comments. And my friend came up with Trickminder.

As for me, I came up with a better name:

Tricken.
