Rosetta's end-user documentation is very poor. I think that if I studied the source code of some applications, I could understand better how they work. However, studying the source code of a large project such as Rosetta requires a lot of help. I'm guessing that the Rosetta's developer resources (listed here: https://www.rosettacommons.org/dev) would help, but that requires a password (ex., https://wiki.rosettacommons.org/). How do you get this password?
I understand that Rosetta is an open-source project. Does that mean that anyone can contribute to its source?
