You may also want to check out Perl 6 Newsgroup Threads of Interest, which pertains to the above mailing lists.
(Note: since Google Groups mirrors these lists, there used to be some sort of problem with posts to these groups through Google not being seen by the subscribers to the underlying mail lists, meaning most people never saw the post in real time. Please update this note if that's changed. Keep in mind that Google Groups is still a fantastic resource for searching perl.perl6.* archives, and for reading threads on the web.)
You can also get these list by email; see (http://lists.cpan.org/showlist.cgi?name=perl6-users) for details (and make appropriate substitutions on "-users" for other groups).
You can access the mailing lists in several ways (we use perl.perl6.users as an example below, make appropriate substitutions for the other cases):
IRC channels (and their archives) are a major source of useful information. NOTE: Please don't unthinkingly interrupt and pester the developers of Perl 6 with questions that you can just as well ask on perl.perl6.users, which they and others can then later answer at their convenience. (As always, it's good manners to search Google Groups and to check archival logs before posting questions.)
