That's my problem.

I'd like to manage two ore three groups aren't sharing their libraries. Some colleagues will use it with most of them using only one of the groups only. To each group I'd like to set up one Zotero account the group members can use to access. There is no necessity to differ between the persons accessing the group/library because they will have reading access only. Therefore it's not necessary to create a special Zotero account for each of my colleagues.
