- Is this not somewhat redundant, given that discussion pages can have
"new section" links, and that InputBox can handle this, to some extent?
- The extension outputs a lot of invalid XHTML, which can *break the
whole thing* if MediaWiki is configured to output the MIME type text/xml.
It doesn't seem to be redundant - based on over 2 years of communicating with wikihow users, they seem to appreciate being able to type the message right below the one the are reading and hit post from the same page.
Feel free to change it if you think it can be improved. This extension works for us, I decided to share it, our users like it, it might not be useful for everyone.
