We have moved the website to another hosting company. During the last weeks we have had several problems with the company providing the service. In fact, the website has been inaccessible some days and we have placed it also in maintainance mode some for prevention. Finally, although the process has taken two months, we have found a company that gives us the desired service at the quality level we need, and we expect to be with this company for a long time if stability enhances. Having finished this important step, we hope we can soon come back with updates.
