Yeah I might do indeed. What is a .eu domain used for? I contacted the trademark and they said lets wait.
.eu is the European Union TLD (Top Level Domain) http://europa.eu/ As for "I contacted the trademark"? Who exactly did you contact? And who told you to "wait"?
The CoCa-Cola company. I emailed there main department and they said I can write to them or phone them.
