Sorry, i dont know the answer , im not familiar with ASP, i could do it with PHP, but obviously thats not a lot of use.
What i was wondering though, if i wanted my to have a box like the one for google, with a search bar, but for a particular website, such as: http://technorati.com/ ?, would i have to wait for you to include that feature, or could i do something like this: http://technorati.com/search?return=posts&q=[THE_QUERY_STRING]
Then your site converts that: [THE_QUERY_STRING], into the actual content of the search field?, catch my drift?
