It's tricky to get email notifications right so that they're not too spammy. Maybe later.
For now, I added this page where you can see your IP logs for the past 30 days:
https://bitcointalk.org/myips.php . You could pretty easily write a userscript to periodically check this and warn you if it's weird. (But don't scrape it on every pageload.)
I don't want to make older IP logs automatically accessible because that'd give a hacker a bunch of useful/sensitive information. But 30 days is probably not too harmful.
The log looks suspicious,
I have been logging from various locations, but some are definitely out of my recognised range.
Country is the same, but very strange IP locations popping out here and there.
I am going to change my password anyway.
This is the minimum required action.
But anyway this log need some double checking.
