Many NCs like me don't have the skill to design a professional logo for their small networks.
It's also not easy to find a service online offering this cheap or for free. I have always been searching for such a link. Where you can pop in, come up with a simple but cool logo in minutes. Most of the links that say make a free logo let you waste your time customizing it but when you want to save it to your PC you find out all what they said at the beginning was a lie. You have to pay. They always have hidden fees but today I stumbled upon one unlike others. When I finished and saved the two logos I designed in less than 30 minutes, I couldn't help writing back to them.
They have a donate button you can opt to use
I hope this helps the less computer savvy NCs like us.
