Through the old CivicSpace CMS.
2 current (D6) ones - cidra.org and jarvissanctuary.org. 3 more D7 projects under development, 1 in earliest stages (might be a D8 project)
No answer yet
Working with Drupal on and off for years, but more on than off now. Currently developing 2 new ambitious (at least for me) D7 projects, including themes and perhaps even custom modules.
