Yes, the user board logo was just changed. We wanted add something that was more professionally designed and to match the logo we have for the user board on our Online Community page (http://amazingcharts.com/support/online-community/).
I think it was probably in the last day or so. I know they recently a created a "user group" icon, and this is somewhat similar. It is all about branding...(probably a good thing).
Oops...just overlapped with the official response.
