When you start your journey with Debian, you tend to have lots of questions. You’ll find some answers in various documentations but there always are remaining questions. Those can be asked on various support channels:

on mailing lists (debian-user@lists.debian.org for the English-speaking one);
on IRC (channel #debian on irc.debian.org);
on questions & answers websites like ask.debian.net;
on web forums like forums.debian.net;
on every other places where Debian users hang out together (on a booth during a conference, during an install party of a Linux User Group, etc.).
