I just wanted to share that I have installed and been running Drupal on DH with no problems. Please note that you have to disable the PHP-CGI global setting on the webpanel. (Well, there may be a way to make it work with CGI, but I gave up after glitch after glitch, and doing a clean install as an Apache module has been effortless. [knock wood])
There were no secret glitches or anything. However, getting the right MySQL syntax to copy over the database was a bit tricky. The Drupal documentation assumes a lot of PHP and MySQL knowledge. OTOH, their discussion threads are very active and helpful.
There’s not a lot of activity here, and when I was considering Drupal there wasn’t much info beyond someone else just saying it was possible (and he had links to two sites to prove it). So I’m just posting this for those considering Drupal for a CMS or blog package.
