I didn't follow KOSTEM Mailing List much since I was so busy working offline on sites. So, I heard that they finally decided to use my logo design as the official KOSTEM logo. So, as promised, here is the Inkscape source file for the logo.
Hope you like it. For those who would like to use my Logo & Branding Design Service, please comment here and leave your contact information. I will contact you as soon as I receive your message.
