Option 1:
If you are referring to seeing your PMs Received and Sent...
It's easy enough already....
Just go to the top of the page just above "Quick Links" (using DarkShadows theme)...
you will see box with "Welcome, YourName."...
Right under that there is a link to "Private Messages:"...
Click on that.... it will take you to your PM page...
At the top of that page there is a box named "Folder Controls"...
In that box choose which PM Folder yo want to Jump to.....
Option 2:
If you are referring to the last Posts that you have made... then click on your name
in the "Welcome, YourName." box...
Then on your profile page click on the "Statistics" tab...
In the "Total Posts" box... you can choose to see your last 500 posts
or your last 500 Threads that you created...
