Where do I find all my posts?

I recently became a member of your site again after a few months of being inactive. You have made large changes to the site and one of the problems I have is that I can’t find a show all my posts button anywhere.

I want to be able to go back to old questions and read the solutions and tips I’ve received.

Also the recent Q&A activity on the side of the support doesn’t seem to be working properly since it fails to show the question I made before the last one. If i go into my profile and check the recent Q&A activity it seems to be correct though.
