I've been putting lots of time in the IVRPA site. Most of it is behind the scenes work to keep things running, and I fairly often get to contribute changes to Drupal modules back to the Drupal project. But now for the first time, I have contributed 2 new modules to the Drupal project, which I will maintain myself.
Provides shortcut paths to current user's pages, eg user/me, blog/me, user/me/edit, tracker/me etc.
This means logged in users no longer have to know/remember their uid, and it makes it easier to link to user-specific pages from a site help page (without resorting to using php to put $user->uid in the link).
