The static 'www' is not well suited to the dynamic community project and updating work of the 'trac'. So conceptually... I suggest moving everything other than the base descriptions (then linking from there out to trac) from these two...
https://www.torproject.org/projects/projects https://www.torproject.org/getinvolved/volunteer.html.en#Projects
out to this...
and then making a subsection or subpage therein for volunteers and the smaller informal projects.
I could see the advantages in that if there was a high degree of involvement in this area (wikis enable collaboration in a way static sites don't). However, in practice I'm the sole person keeping the page updated. The static site allows a nicer presentation so think I'll leave it there.
The wiki I cited is pretty old - is there anything from it we want to keep?
