A thread like that seems pointless, because the Essentials section is made of questions. A thread for multiple questions is harder to search, and would become cluttered with back-and-forths when some of the "simple" questions inevitably grow into something quite convoluted due to the discovery of underlying problems or poor understanding/communication of answers.
It would be nice to have more guides on how to use Essentials, as well as more guides on how to make games. That would help the newbies out. I wouldn't know how to write them, though, because I know too much to imagine what a newbie would want to hear.
Do you think it would be a good idea to start a "Ask a question; get an answer" kind of thread in the PE forum? Specifically for people who are just starting with Essentials and don't entirely know what they're doing, or anyone who has a question too simple to warrant its own thread. I don't see one at all that already exists, so I thought it might be a helpful addition.
