I believe this fund will give activists a lot of bang for their buck. I just chipped in $50.
Clarification update (4/2/10): The current fund raising goal is to pay for legal defense of "sovereign curtis", who was recently arrested in Nashua, NH, for "distribution" of pot (he allegedly handed an undercover cop a pot cigarette) -- a felony, believe it or not.
Here are a couple videos of the initial event, the day before:

And of curtis' arrest:
Note that the cops refuse to identify themselves.
