Welcome aboard! Let me just start off with this- I've been a member for almost a year now, and never bothered to post my playing until a couple of weeks ago. I lost out on so many good tips and help from everyone on here, and I regret it immensely.
So if you're like me and feel a bit shy about posting your playing, I strongly encourage you to just try it once- you'll be glad you did.
Have fun with the lessons!
