The quickest way to contact us is in the IRC channel. If you do not have an IRC client, HydraIRC is an excellent choice on windows, as is irssi on Linux.
If you need to contact us, for whatever reason, by other means, you can find more information on our user pages:
Additionally the perl-doc-cats org has read/write access to the repos, so in a pinch you can also try contacting them via github.
You can also contact us by email: info (at) perl-tutorial.org
