I'm not sure if this is possible, but:

I have re-designed the Messenger Plus! Support website, and it didn't work very well in Internet Explorer or Opera, so what I did, was create a new folder, called "IE", which runs perfectly fine in IE & Opera. Is there anyway that I could automatically send those with IE/Opera to http://www.mpsupport.net/ie/ rather than http://www.mpsupport.net/index.php?

I don't mind what type of code is used... Saral has a code similar to this, where, if the person is using Internet Explorer, then the image that is a .png changes to a .gif, so it is still transparent.
