I think as far as research availability, I would leave it to individuals to decide whether to put their work behind a paywall or not. I'd just note that if someone can't talk about their work in a society -- for confidentiality or national security reasons -- their participation will be kinda one-sided.>group needs a more clear-cut purpose
I'm thinking of it being somewhat local, and focused most on the needs of independent scientists, and value diversity the best I can. I would focus on one kind of science, but I do work with plants and animals and astronomy, along with computer science, and I don't want to create a lot of groups. There's always an option for sub-grouping if necessary. Really depends on if anyone joins, I guess.
Sorry, still been very busy with one of my jobs, just trying to survive. I think in a few weeks I will be able to get back to the scientific profession.
