Interesting that it has tubulars on it. I don't know the Atala lineup that well but I suppose it's possible they were using tubulars on some lower end models or somebody changed them at some point.

To change your "Newbie" handle, go to User Control Panel (upper right of the screen) -> Edit Profile -> Custom User Title and change it.

Also for pictures, upload them to a picture website like Photobucket or similar and then link to the URL of the picture. Just click that yellow square on the editor that looks like it has mountains on it and enter the address to the pictures. Then you can put pretty much any size you want.

Post some bigger pics of the frame and components and maybe somebody can get a better idea of what we're looking at.
