I have one helpful solution to the problem when you're reading a page/post and the content contains a set number you're not familiar with. Instead of opening another page and doing a search, I've implemented what Internet Explorer calls an "accelerator" for Bricklink and Brickset. You simply highlight the set number and you get a popup menu which provides shortcut ways of searching on Bricklink or Brickset.
With the Bricklink accelerator you also get an image preview. See the attached image for what it looks like for the Bricklink accelerator.
To make this available to others I need to host the files (an html page and a couple of xml files) on a website. I don't have one myself which is publicly available. Can anyone volunteer this (or convince Huw to host on Brickset.com?)
