I had a couple problems with your MSN plugin.
1. It wants Windows MEssanger 4.7 most people with MSN 6.2 installed doesn't have windows messanger already installed. I am using the latest version of MSN plus and MSN 6.2
2. comctl32.ocx is missing from your installer I had to go to www.dll-files.com I'm here at school on Windows 2000 pro with Service pack for and IE 6.01.
3. Excelent work I've been looking for something like this if I had cash in my paypal account I'd send a couple bucks off to ya
I have attached the comctl32.ocx file here as a zip file it came from
