The new box also searches my other vanilla-ish 'gateway' blog at mitchmen.com which may be useful for artist and model names. It presently has the limitation of producing duplicate entries where the same word is repeated in a post but occurences in titles are all listed first.
Anyway I plan to keep both options for the time being
(mmmm yes please!)
There's a list of labels in the sidebar, but for size reasons this is not a full list.
Finally there's an artist index tab at the top of the page
If you have difficulty using any of these search options please let me know (preferably via the comments facility) so I can try and sort it out for anyone else who might want to use it. Unfortunately I don't have time to keep checking things like that, I must rely on the help of my readers to tip me off. Thanks.
