There are regular study/tutorial sessions organized via the mailing list and generally posted on the schedule page.

You can always ask questions on the mailing list! It is a happy friendly place.

We have also colonized #learncs on irc.freenode.net. This is an IRC channel. Popular IRC clients include Colloquy (os x), Irssi (os x, *nix), and Trillian (windows). feel free to google for others! if you want interactive help, IRC is a good environment to seek it in, where real-time dialog can take place and others can learn from your questions as well.
