The value of CD is clear - 5 $'s is a bargain for the hours of entertainment and education that I have gotten from the forum. I assume the same is true for the students, but it is probably more difficult for them to bear the expense. If there were a way to make access free for students but charge non-college mentors $5 every 6 months, I suspect that CD funding might be a non issue.

Seems like this thread may be an informal method of enacting such a policy.
