There is no by-poster search feature in query.php (the parent of Ask The Tropers, You Know That Show, etc.). The general search feature can find your name but only if it's in the body of the OP of the topic.
You can use the Google search, however, as a workaround. In the search bar, enter your handle (Guitaroftime0116), followed by the text "inurl:query.php", without the double-quotes. You may have to persuade Google that you really meant to do it.
Edit: Hmm, when I try, it returns a reference to a page, not an individual post. This won't work because YKTS will have moved on, while Google's search index is usually at least 24 hours behind. Sorry, I guess you just have to go page by page and Ctrl-F your name.

It's self explanatory.
