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?
