Since the site came back I don't know what is happening with the written part of the lessons. I have completed some and they used to appear on the side of 'myppage' and people would give feedback, now, when I press 'post' after writing it, that's the last I see of it! I can't find them posted anywhere and therefore cannot get any feedback .. can anyone tell me where they go now?
I can't tell you where they go except cyberspace. They no longer generate a post when you submit them. Your answer may, indeed, be stored in some database somewhere, but they no longer (at least, not for now) generate a public post that members of the community can comment on.
I'm trying to talk them into, at least, posting the answers to the questions somewhere, but so far no luck with that either. I think we're going to have to be patient and wait for some of the more challenging issues to be addressed. In the meantime, if you have any questions about the exercises-post a question in the appropriate forum category. I'm sure you'll get better answers than you got from the few of us that reviewed those posts, anyway.
