The Perl 6 Tricks and Treats newsletter has been around for a while.
If you are interested to get special notification when there is new content
on this site, it is the best way to keep track:
This is a newsletter temporarily running on my personal site (szabgab.com) using Mailman,
till I implement an alternative system in Perl 6.
