Yes! I don't think people who started in the modern age can even relate to how amazing this was, to have a documentation site with a built-in user comment system collecting errata, tips, pointers and snippets (even as erroneous as they sometimes were)...

This was before the embarrassment of riches that we have now...

- before proliferation of open source examples on GitHub,

- before StackOverflow,

- before jsfiddles,

- before snippets on gist or pastebin

- before very common web forums (many of which were eventually written in PHP in fact)...

- before fantastic search results of google...

Best you could hope for when you got stuck? Someone's personal web page, or usenet and mailing lists...
