Greetings and thanks to both of you for the advice, the user-name bit wouldn't matter too much as I haven't got anything in my songbook yet!
The only part I wanted to change was to display "wooddragon45" rather than "wooddragon" so if it's a hassle to do then don't worry about it...
I tried the upload again but having the same problem, so I'll try the avatar upload again after 24 hours as you advised, the dimensions are
59x59 and the file itself is 4.24k in .jpg format...if your site prefers a different format I can easily convert it...
