Where AreMy Postings

I probably asked this before but I can not find it. This MY WORKSPACE is not showing me all of my postings. It shows a couple. I have dozens out there. From some months ago to years. Ones still opened too.
How can I find “ALL” of my postings and keep them on my page. Like the ORIGINAL discussions page we had before. The other problem with that is it only showed me the last 20 postings. Not all of them. This new site is not even showing me those 20.
Can anyone assist me? I am looking for opened and closed postings of mine that I need to look at.
Thank you.
