Welcome to the forum. I hope you find helpful, informative and enjoyable.
So that you don't continue to get people asking you what your proper name is, because most us use that on here, you can go to Edit Profile (under 'Forum Actions' on the Menu Bar), or you can just press on 'Settings' on the menu bar right up at the top right of the window. Once there you can enter the name by which you wish to be addressed under 'Real Name'. Then it will appear underneath your Username in all your posts.
