I dunno if anyone found this out yet, or if it even works with different browser.
As the title says, I found a way to use the J&D Wiki's search engine without actually having the Wiki opened! Quite useful I must say, considering I go here quite often and such.
Either way, Im using FireFox (newest as far as I know) and have the Google search bar in the top right. You might be using Internet Explorer and Bing, but really now, get that crap of your PC and install FireFox! IE/Bing suck compared to FF and Google. Now, its easy, just click on the small arrow next to the Google favicon in the search bar, a drop-down list will appear. Then just pick the option saying "Add Jak and Daxter Wiki (en)" or something like that.
Tada, you know can use the search engine without even opening the Wiki :D
