I just tried to include a link in a comment (to question 13831 -- would appreciate it if someone fixes it), and failed miserably to get it to format correctly. the link is to a document in an ftp://... area, not http://... I tried to follow the help suggestion, but that didn't improve anything.

On earlier posts or comments the html formula <a href="...">...</a> appeared to work (although i noticed soon after that someone had edited it but i couldn't see the underlying code). i haven't checked the faq about this just now, but i don't remember seeing anything useful there. the "Code and Preformatted Text" page does say that the html syntax can be used, as does the "How to Format" box on the "ask question" page.

Are the conventions for coding in comments different than those for questions?

Help, please.

  • You just can't use any HTML tags in comments, just markdown. And as TH observes in his answer, HTML entities are also not supported in comments. Mar 19, 2011 at 8:31

  • @TH: What a coicidence! As to what his joke is, it surely is that one page in that chapter has a different running head. I never noticed that, and I wonder how many did. Mar 22, 2011 at 9:02

They seem to be the same.

I've noticed that HTML that works in answers doesn't always work in comments. For example ε-TeX (_&epsilon;_-TeX) doesn't work.
