I've been playing with the site and perhaps sharing what I have found might help.
a) when you arrive at the site, the cookies are not working, so you will need to log in
b) When you log in, if you see just a list of replies, click on "Communities" at the top, and then AF Association, this will take you to a much easier home page
c) It will still show activity, and to change this, either click on questions or Posts (Posts are the new name for blogs)
d) Note now that the answers to questions are upside down, most recent at the top not the bottom, but annoyingly replies to an individuals replies are still with the original reply.
e) There is still lots of stuff not working, so do post if you find something, there is no "contact us" button for the web master annoyingly. You can email firstname.lastname@example.org
Lastly I have emailed and spoken to the team they say they are a very small team, and they are trying very hard to get it up and running, I have expressed that they really should have consulted first, especially on the site navigation, but no point living in the past, let's move on and help as any people as possible.
Hope this helps
