I've created a series for complete beginners in which I'll be going through all the account levels (which experienced players have probably forgotten about) and explaining the basics of the game and the interface. I've created this topic separately from my main video topic so that if you know of a brand new player, you can send them here and they won't be confused and confuddled by all the other content. Here's the link to the playlist itself:

I'll post the individual videos here too in case you know someone who needs to know about a particular basic topic.
