I am still navigating this system. Getting there little by little.
See if clicking on the following link gets you to your thread list
The route seems to include getting to your User Name, clicking on that, and then on "Activities".
Hope this works for you.
Stupid me... I was clicking on "Inbox and Activity", but activity is really under "View Profile".
Thank you again,
Glad that worked for you.
One of these days I will figure out where everything is now. Still working on that.
