Hi CatePDQ! Welcome from Southern California!
When I first started on QB I just started reading all the posts and after a few days I was using the Search window up on the right hand side of the page, just past the word Help.
Then to see what was available for instructions I looked thru the Tutorials.
You can see when people joined by the "Join Date;: under their name.
Enjoy! I have learned a lot from the folks here.
