I've read through the threads but it's surprisingly difficult to fit everything into place because the posts are (understandably) out of order. I'd need to read one or two posts in one thread, then one post in another thread, then two posts in a third, then back to one in the first thread, etc. to really understand what's going on, and frankly I can't seem to do that.
Can anyone summarize what is decided and what's undecided and what's simply unknown?
