No, This is FAR from being an addon. All you\'re really doing is running a url with the search format. You\'re not actually doing anything that is saving someone time.
Normal Way
1- Open Browser
2- Type Url
3- Type Search
4- Browse Results In Browser
Your Way
1- RightClick
2- Find Search Engine Popup
3- Type Search
4- Browse Results In Browser
Now, Maybe if you were using sockets and actually getting the results and links and putting them back into mirc, that might be more of an addon. Every person that wants to throw a couple echo commands some popups and a few runs, thinks that they made something incredible. I\'m sorry. But you didnt.
