Since it is just idle brainstorming, let me give some idle thoughts, which i am sure you have seen before in the earlier discussion of e-cpms.
1, To save money, members could choose to receive the newsletter by email, thus saving money and environment.
2, Journals are interesting, so far but too expensive and too deep or academic, only for experts, perhaps members who really want them should pay for them , from what I saw, they are easily worth $50 each (but I won't want it since I am not so deep into it ) and many libraries and organizations would want them.
cheers
