I viewed the tutorial but it was a little vague. I tried doing what it said but nothing happened other than I could see little dots. I used the lasso tool and got part of the background and moved it to the second line of text and was able to fix that but the top line goes over two different colors and it's an image and I tried to do the same thing there but couldn't get it to work. The videos weren't a lot of help either. Anyway you can see where I'm at now.

I tried doing this and nothing happened. Am I supposed to use this like an eraser or what? I guess I need to view the tutorial before I ask. Just need to remove text from a banner so I can redo it for a forum template I'm working on. The logo is attached. I need it to say Tangisurf.com Tangible Products Surf Forum
