Account Activity

there used to be a button that took me to a page where I could see all the discussions I opened displayed in a neat tidy table and was able to see the status and updates of each discussion. now all I can find are my latest posts. Is it possible to bring that page back?

p.s 
personally I find wide pages tiring so I actually like the white space on the sides that everyone seems to be complaining about. I think it makes it easier to read and follow the threads. having said that, the white space does seem a little over whelming and can use just a little less of. also- the margins on both sides of the content are uneven.
