I'm pretty sure most of us would prefer simply publishing a link, and clearly there's nothing to stop people who want copy delivered to their mailbox by signing up.
I don't know enough about the PSF communications strategy to know whether the emails will include full copy. In any case, I'm really glad it is developing a broad channel for providing information about the language and its users, and wish the newsletter well. I'm sure the feedback from this list will be helpful.
As we all know, the PSF is a developing organisation. I can certainly hardly recognise the somewhat stumbling bunch of geeks that I joined in 2003. More strength to its arm.
