The CG5001 is for the TM 5000 series, not the TM 500 series. However, a template doesn't exist for the TM 5000 series, so it wasn't just a one character change. Indeed, the first line of the article is nowhere to be seen when the article is opened in edit mode.
I (Kurt) am concerned that the templating of pages adds complexity and reduces the likelihood that non-programmers will write for Tekwiki. Most people who request accounts to edit the wiki never submit any changes. Are they put off by the complexity of the system? I don't know.
Maybe some kind of "howto" document would help.
