internationalization drupal7

I need to create a site totally translated to 10 languages, I loaded all the relevant modules and have it working but with many errors.
I really don't know where to ask, because the IRC channel is only for dev talk and I don't think that my beginner questions would be welcome there.
Drupal forums are not user-friendly, Drupal Answers maybe, would be worth a try.
Anyway, here is my first question: how do I get nodes translated?
I mean articles, whenever I write one I see all languages crossed out.

Has anyone out there used LingoTek with Drupal for Internationalization of a D7 website? If yes, and you wouldn't mind sharing some of your experiences, I'm reachable at jsheldon@mit.edu.

Thanks!
Josh
