You don't need to post another question to say 'thank you'. :)
Just go to your original post and put a message in the Answer box. It is nice if you pick a 'Best Answer' for someone as well. It says 'select as Best Answer' or something above each post and you just click it. Glad we helped anyway.
^^^^ P.S. Just by 'answering' your own question you will find the original post appears at the top of the list of subjects on the right-hand side and so it will be seen and checked by people who answered.
Your singing seems pretty competant to me.
To me, your style may not work best with Ed Sheeran songs ..perhaps try some Eva Cassidy songs? Either way, keep it up :-)
