Hello! [snip]
We're particularly interested in three things: (i) making Darcs faster (ii) building nice GUI tools and (iii) working seamlessly with SVN/Git repositories [snip]
Both of these roles are called "mentor" in the Google system. Putting together a good team of mentors before applying as an organisation is helpful towards us being accepted into the programme.
I'll volunteer as a mentor if it helps.
Darcs users: if you have a few spare hours this summer, this would be a most excellent way to participate. Stick your hand up :-)
I am volunteering as a mentor as well. My schedule is too crammed to go the student way this year (and, probably, any future year). I am particularly interested in mentoring (i) kinds of projects mentioned by Eric above, but other will do, depending on what prospective students come up with. Yours, Petr.
