At the University you may belong to a particular working group; for example, in your department, service or other such group. If you belong to one of these 'disco.uv.es' working groups in which you share spaces, the group can ask the Servei d'Informàtica (SIUV, IT Service) to create a blog for the group, independent from the blog of each user.
Example of a group blog: http://grup.blogs.uv.es
PAS adminstrative staff or PDI teaching staff members can request a group blog associated with a disco.uv.es working group. So if a user belongs to a disco.uv.es group called 'algebra', a blog can be set up for this group called http://algebra.blogs.uv.es.
