Hi there,
in these days some Zotero-Addicts in Germany, especially with librarian background, initiated a virtual Zotero Meeting which shall took place from time to time. In this case I just opened the library for member editing and changed some admin roles for trusted persons. Because: This group shall be also a place for sharing training materials for refman-tools, especially - but not only - with Zotero-context. Feel free to add! But please consider: "Public Open groups cannot have file storage enabled." It's the best, you upload your personal fulltext materials to a public server, e.g. ftp-server of your institution, and link to them via the item-metadata.
Thanks in advance!
Matti
