There are lessons, in the form of several videos, but I'm not sure if there is a list of them somewhere or how to find them (they were made after I had been a member for several years and had already learned everything I needed to know the hard way, so I never bothered to look them up). If you contact a greeter (at least one will have left a comment on your profile when you first joined), they should be able to point you to the videos.
I'm not going to say "yes, this is the way WikiTree runs" because I am afraid of being censored under the new G2G rules for saying something negative - CENSORS, PLEASE NOTE THAT I WAS VERY CAREFUL TO *NOT* SAY IT. By all means, feel free to just ask here about anything - there are loads of people just dying to help and, between all of them, everything about WikiTree is known.
Suggestion - an easy way for you to store away answers is to click the large grayed out plus sign at the top right of your question - that will add it to your "favorites" list. You can select G2G Profile in the dropdown menu at top right of the page and there will be a tab to display your favorites.
