By “symbols” in your post above, do you mean “letters of the alphabet”? Have you learned how to pronounce them? Have you ever studied anything on your own before? Is English your native language?
We’d be eager to get you started, of course. Before we do, though, I’m going to send you an email about your username. We have a policy that is rather strict about using our real names. I’ll send you the details in an email in a few minutes, and then we’ll get you sorted on direction and what you do next.

Good luck!
