I think calibre is by far one of the most useful and used programs that I have. I also really appreciate that the program is updated and actively developed so often. As such, I donate yearly. This last year, I realized that there are many more individuals actively involved in the development. Out of curiosity, I was wondering if someone minded telling me how the donations are divided up since I imagine that calibre's development is probably filled with many volunteered hours plus hosting/server/bandwidth/equipment costs.
