Drupal non-issues: a content type named 'type' & eliminating the title field
You know the old joke about a guy who goes to his doctor and says "it hurts when I do this" and the doctor responds "so, don't do that"?
Two examples of "so, don't do that" from Drupal are "Unable to add content to a content type named 'type'" (link) and "Do not require a 'title' field" (link).
I left comments at both links.
