click on your username at the side of your post above. it will come up with a list of options - one of them will be "find more posts by *yourname*".
If you click on this it will run a search and show all of your posts, as well as which forum and thread they are located in.
You can also run an advanced search: Use the search by username option, type in your username and ensure you choose "show results as posts" and not as threads. The advanced search is a link in the search option at the top of the forum.
HTHs.
PS - this would have been better posted in suggestions and questions
