Good idea- maybe we could just send out the calendar and the other articles could be placed each month on the website for reviewing. Anything that comes up before the next months calendar could be a email blast to members.
My 2 cents worth.
I do look through the newsletter, but don't see a need to have it published as a separate document. I'd vote for just putting the calendar on the website, and then articles can get published on the website as they are ready.
