Ok, I searched for "portable" excluding "dishwasher" to look at old portable threads. Any that don't have a 20,000 or higher number load fine. I can usually look at the cached version (when available) of newer ones, and pictures usually work. If I click on the link straight up, it goes 404. Click link below. It's 404 for me, both at home and work.
In order for threads to be searchable in google you have to wait until they move into the Discuss-o-Mat archives and then google craws the web over the Discuss-o-Mat archives which might take a month or so. Threads that are not in the archive have changing URLS with each reply so you will get a 404.
And just to experiment try putting in "Maytag A-806 For Sale" in the Super Searchalator Search field this exact wording or phrase:". Be sure to click on the checkbox "Check to only search the Discuss-o-Mat Archvies" as well. Thread 21001 comes up and works just fine, it just takes some time for google to catch up.
