Those of you, that used Diigo for the administration of their sources of Internet, I would like to refer to a very interesting new function, the possibility, of furnishing groups. Within these groups you can collect together with other sources to a certain topic and furnish even a forum, within whose framework to the appropriate article opinions can be exchanged. That offers numerous potenzielle use possibilities within the ranges school, teachings and research. This all more than - as you an instructive Flash Tutorial shows - which is very easy application. Who with Diigo is new and itself more broadly about this service and its use to inform would like, finds here, likewise in the form of Flash Tutorials, thus to small films, all necessary guidances. I can only recommend to you to try Diigo out once; it is for me at present best service of this kind in the Web.
