Andy are you typing bookmarks within this thread, or in the top right corner? Take a look at the area where the number of pages are listed for this thread and below you will see the option, "search this thread". When you click on that it will give you a search bar and there type "bookmarks". This will give you all the relevant posting only within this thread and not the entire talk site. The topic you are looking for has been discused in this thread (sorry, not sure which page) for sure so you will find what you're looking for.
