When it came to WYSIWYG Editor Input Formats, there was always a great divide between Filtered HTML and Full HTML. Full HTML is intended for admin use only because it allows any HTML tags and attributes to be used. The Filtered HTML format lets authenticated and/or anonymous users add content safely by limiting the allowed HTML tags that could potentially be harmful to the site, or to the design.
The Drupal community has grown to be huge, something that was driven home by the ocean of Drupalers greeting me at the con each morning. A great thing about having such a large community is that it means more projects, more than any one person can keep up with, more than one person can even hear about.
