For some time now I've been working on a Drupal site that consists mainly of scraped content from a proprietary, ASP based CMS from the late nineties. The Simple HTML Dom Parser, used from within a drush script, has been invaluable. It made scraping the old site content and importing it as Drupal nodes a relative breeze. (No access to the database used by the CMS, boo!)
Part of setting up the new site is importing users and their content profile nodes from a different Drupal site, that was setup a year or two ago to manage an event.
I had hoped there would be a way for me to export these users and their profile nodes from one Drupal to the other, but though I found modules to export one or the other, I might still end up with profile nodes that were no longer related to their users. Of course, that's pretty useless.
When I remembered I was also supposed to add all these users to a simplenews newsletter, the proverbial light bulb came on.
