I think you can go back indefinitely if you type your name into the search feature and select poster. At least that's what wirestripper said. Just figure out how many posts you have per page and how many pages you have.

Is there a better way to count the pages? One that doesn't require opening each and every page to get to the previous one? That could be tedious and error prone when you are trying to get an exact count of over 10,000 posts...
