thank you. I just used
The GIMP 2.4 RC3 (GIMP 2.2 is the latest stable version) and to make the circle thing, its kinda took awhile for me to figure this out sense gimp is not as good as photoshop. but ill do my best to tell you. i made a transparent layer then i took the circle selection tool and made the shape of circle i wanted. then filled it with a color. then make a slightly smaller circle on top of that layer. fill it with white. then tilt that circle jsut slightly. then click alpha to selection and delete that layer. then with the selection still active take a big eraser and eraser every thing in the selection. then u have your basic circle.

i hope that helped. if u have any other questions let me know.
