This used to be a website for Gnus users. It no longer exists.
The URL used to be http://my.gnus.org/ and the motto was “To boldly frobnicate what no newbie has grokked before.”
You can try the #gnus channel on Freenode, if you want to talk about Gnus on InternetRelayChat.
It seems that this website hosted formerly the Gnus frequently asked questions (see GnusQuestions). The FAQs are now part of the Gnus distribution and you can read them in the info page: use
C-h i m gnus RET to get there. You can also find them in their section at the Gnus manual. The FAQs are in the file gnus-faq.texi from the Gnus CVS repository (); see it here: gnus-faq.texi
