The banner must be static (no animation), 728x90 pixels. Banners with a white or light border must include a dark/black 1x1 pixel.
The design must contain the logo (see attached file), a tag-line and a strong call-to-action.
The design must respect the design aspects of "banner ad best practices" as outlined for example by:
The winning design must be in an open format (.SVG or .XCF), where I can change the text element on it, as I will publish it in multiple languages.

"call-to-action": something like "register now", "signup now" or "post job now"
Feel free to keep or change the wording of the "tag-line" and "call-to-action".
For any questions, ...just ask. I'll be happy to answer. :-)
