We used to be able to click on a members name and view previous posts that they had made. This is not possible after the update. Was it a deliberate choice to do this?
You can still do this. If you click on a users name a pop up box should appear. If you then click on the users name at the top of the pop up box it will take you to their member profile page.
On their member profile page you will see links to latest activity, postings and about. If you click on postings you can then see a list of posts that they have made.
