Re^2: Should I register a namespace in PAUSE before every cpan module upload?

[ww]

Please don't use square brackets in the manner above. If your taste in formatting footnote pointers runs to [...] use &#91;...&#93; because the local variant of HTML uses square brackets the way standard HTML uses <a href=...</a>.

That means you could also have created the link thusly:
&#91;https://pause.perl.org/pause/authenquery?ACTION=peek_perms&#93;
which would display the url, linkified;
or
&#91;https://pause.perl.org/pause/authenquery?ACTION=peek_perms|<super>1</super>1&#93;
which would render as ^1. -- a superscripted 1 -- and thus would serve as a link to PAUSE as well as a pointer to a footnote... probably not what you want, here, but useful in some cases.
