There is no accurate registration date information for the first couple years, the first couple thousand users, of Drupal.org's history. There is even a discrepancy between the posted "Member for" dates and the apparent launch of the site.

Between users http://drupal.org/user/2119 and http://drupal.org/user/2120 the date of registration (time on site, or "Member for") jumps by two years and two weeks.

You may know about ctrl+shift+R for reverse case-insensitive search (or whatever it stands for) and that is still useful if you remember one very unique keyword from the middle of a command.

Git log shows you all your commit messages and the revision hash, but often git log would be more useful showing files changed. (You should still try to write commit messages as if the reader will have no context except, at best, the project itself.)
