In a moment of distraction, I have created two Firefox search bar plug-ins. One for searching the Singletrack Bike Forum and the other for searching Sheldon Brown.

Click the links to add if this is of any use to you whatsoever.

And to pre-empt the expected comments – yes, I really do need to get a life.

It works very nicely. Nice one.

I also made a couple for Wiggle and Chain Reaction.

They can be found by searching from the same pages.

It's called the Mycroft Project. In a minor piece of trivia for those who might be interested, Mycroft is the name of the brother of Sherlock Holmes. He is portrayed as an omniscient (having complete or unlimited knowledge, awareness, or understanding) yet physically indolent character.

Cool!

Does work well but as it hovers not far from the actual search function not sure I'll use it.
