How to contribute to the pkg_* tools project ?

[Lockless]

Hello,

We (Lucas <Bobby> H. and Alexandre <Lock> C.) are two young students 
from France. We have a quite good theoretical knowledge of C programing, 
but we would like to improve our experience in real projects. So we 
looked at the Projects Ideas on the FreeBSD website, and finally found 
out that contributing to the pkg_* tools could be great, but there was 
no e-mail to contact on the page.
So who could we contact to get more informations about this project ?

Best regards,
