What would signal would Harry think best? Something you could detect at the time of signalling, like a broken toothpick in your pocket, or a signal detectable safely in the future, like a penmark on the inside of your pocket? Probably both.
A rememberall.
Surely this would also be a relatively high priority for his research too. In fact Harry explicitly made a note to himself to research mental magic near the top of his todo list. That should have turned up a device or spell that detects obliviations and he should be in the habit of using it on himself regularly. Which reminds me about the research he is supposedly doing. What has he discovered? What useful spells has he learned? He's supposed to be a genius of near-Hermione level academic skill and far more strategic thought. When are we going to start seeing him pull out awesome, practical magical knowledge or skill?

And somewhere, someone begins thinking paranoidly, 'yes, Harry has made very little practical progress, compared to how much time he has put into scheming against bullies, breaking into Azkaban, and fighting Ender's Game - and isn't it interesting that all 3 seem traceable back to one particular person?'
Update: Discussion has moved on to a new thread.
The hiatus is over with today's publication of chapter 73, and the previous thread is approaching the 500-comment threshold, so let's start a new Harry Potter and the Methods of Rationality discussion thread. This is the place to discuss Eliezer Yudkowsky's Harry Potter fanfic and anything related to it.
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: one, two, three, four, five, six, seven. The fanfiction.net author page is the central location for information about updates and links to HPMOR-related goodies, and AdeleneDawner has kept an archive of Author's Notes.
As a reminder, it's often useful to start your comment by indicating which chapter you are commenting on.
Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:
