Hi,
If you click on the Profile button on the top horizontal menu, it will bring up your account where you can edit a whole bunch of settings.
On the left hand side, the 2nd option down under the first box "Profile Info" is "Show Posts".
If you click on that button, it will bring up all of your posts in chronological order. There are three choices - all messages, topics (ie. topics that you have started) and attachments (where you have attached a file to a message) although that last one might not be as useful.
Hope this helps.
cheers
