A brief tutorial on PaperBox Cite
Check it out at http://www.paper-box.co/manual/
I find PaperBox very convenient by allowing me to synchronize paper collection on different computer, and organize them easily with tags. The integration of citing function makes it more competent so that I do not need to organize papers with one software and cite references with another.
