The application I save most of my bookmarks in is NetNewsWire. I'd like to be able to do this with BookMacster. I found a couple of links where people have used the script menu with a javascript from other tools:

I tried this recipe with the BookMaster javascript without success. Is anyone using BookMacster with NetNewsWire? Any assistance would be appreciated.
