With much help from LenAnderson i've created a greasemonkey script that searches posts for your username and highlights the subject title of that post (i.e. Re: Thread title) It also has a beta feature where you can search using a keyword in posts, results will return with a popup and highlighting the subject title of the posts in orange.

If anybody installs it let me know what you think
