First, I'd really like to thank Anoop Nair and Pranoy Ray for their help with: Logo needed for community ads! and Let's work on our logo! (Improving on Anoop Nair's design).
Now in addition to the more square-like format for community ads, we are also allowed to advertise MMSE with banner ads. We therefore need volunteers to help make some logos/ads in the banner-type format, so that we can advertise MMSE in this way on other sites such as Physics.SE and Chemistry.SE. I recommend following the same collaboration format as for the above cases (make a freely editable Google Drawing file, and place all files/images on which it depends in the GitHub folder for the logos).
