    A super professional! Peter Heck supported us very quickly and perfectly with the creation of a project website for an EU-funded project on energy efficiency in industry, "EU-MORE". Flexible and always available, requirements such as a 2-step forum for users on the backdoor of the website were immediately understood and a functional solution was implemented as a plug-in. The entire website incl. forum implemented in the pre-Christmas period (!) within < than 4 weeks...and everything runs & easy to use - chapeau! Gladly again, I can only recommend! Tomas Jezdinsky, Market Research Consultant for ECI European Copper Institute, thanx on behalf of the entire EU-MORE project team!
