I looked through the ads on your site, and none really seem to go with my design. I don't want to use a boring text ad, either. I used an online tool to create a button that I'd like to link to FQ along with some descriptive text. After reading the terms of service, I just wanted to check if it's OK if I use this button. If so, feel free to add it to your library of icons/graphics.

I'm happy to adjust the colours as necessary to fit your branding (I just took a stab at something close to your purple).
