Go to your profile. You can click 'My Profile' at the top or click your icon or name on any thread you've already posted to.
There are lots of different things you can find here. At the top left you will see "Find latest posts" and "Find latest started threads". These will list them all.
I also see "View Forum Post" when I click your name above your icon in this thread. However, I notice that doesn't seem to work when I am not logged on, so not positive what criteria must be met for that to work.
