Not for nothing, but why would you want to make a browser not allowed in your forum? Many people still use IE, and if you want to reach people and add your forum to search engines, you need to allow IE. Bing is getting more and more popular, you need the forum accessible to people using the most popular browsers. Sorry, but IE is one of the top three.

IE is the most popular browser, you will loose like 50% of your users
