All of this that John has just posted is very informative, but I think it doesn't answer Joe's request for a more elegant Google search link specifically for Mudcat.

If you just follow the link I gave above, Mudcat advanced Google search, and enter "I've already strained my brain here" into the "this exact wording or phrase:" text box, Google will point you to John's last message posted about 90 minutes ago. (Should work equally well with any browser and no toolbar is needed.)
