> How do you go about it? Is the bugtracker a textfile or do you use an
interface?

I look up the bug list on

https://debbugs.gnu.org/cgi/pkgreport.cgi?package=emacs;max-bugs=100;base-order=1;bug-rev=1

You can also subscribe to the RSS feed if you like:
http://rss.gmane.org/messages/excerpts/gmane.emacs.bugs

More variants of the debbugs RSS: http://dir.gmane.org/gmane.emacs.bugs

There's also a debbugs package available on GNU Elpa to review/reply to the
bug reports from within emacs (I haven't tried that yet).
