There already was Google, Yahoo and MSN support, but I went ahead and added Bing support to the [search] BBCode too since it seems to be giving pretty good traffic these days... For those that don't know, it works like so... [search=bing]search for something[/search]
Bing is really giving traffic, even more than yahoo. (to my blogs ofcourse) This new BB code will surely helpful to users. BTW i was not aware of other search engine BB codes... ..
