Hurd contribution in GNU Mach Code Cleanup

[faif]

Hello,

I apologise if this is not the right list to write about this issue.

We are 2 friends who are interested in contributing to the "GNU Mach Code 
Cleanup", found in 
http://www.gnu.org/software/hurd/community/gsoc/project_ideas.html. We'd like 
to do it for both GSOC and voluntarily afterwards, but for now we can start 
just voluntarily to see how it goes.

Just a couple of questions:
a) Is this task related with debugging also, or just fixing warnings and 
improving C code?
b) Do we need to register somewhere before starting?

Regards,
Athanasios.
