Nearly a year ago I broke down user_load() and user_save() in Drupal 5. I had to put together workflows for a number of jobs, specifically integrating the creation, instantiation and updating of users with an external system.

EditInline was first discussed here. It's a Drupal module that provides your site with handy editing links, inline with each node title, which rather than taking you to a separate editing page use a lightbox overlay on the current page to provide an inline editing interface.
It's currently in alpha but available under GPL on the Torchbox public subversion repository.

Beth Kanter advocates Creative Commons in the latest post on her blog about not-for-profit organizations and social media. She discusses how she's managed to introduce often quite recalcitrant nonprofit sub-sectors to the concept.
