According to previous experience a webpage built up by the course providers/study visit organisers can be essential to support continuing and sustainable networks between the participants. The following webpage structure tries to provide you with some ideas on how to build up a properly designed and functioning webpage. None of the elements are compulsary, of course, but all of them can help the participants to be better prepared for the course/visit, to estabilish contacts prior to the course/visit and to enhance the possibility of a longterm professional co-operation after the course/visit.
If your institution already has a website, creating a subpage can't be a problem. You may also decide to create a new webpage for the purposes of the course/visit. In this case you can use the existing framework systems to serve as a base for it. You have several options, most of the framework systems can be applied free of charge.
Please, browse this model website to decide wether the proposed elements are useful for your professional purposes.
