@ those who suggest the banner/splash method:
I just don't understand why you would want to say "Hey, welcome to our site... this site is all deticated to an old unupdated version, we have a new version too, but you'll have to click to it first because we like to confuse you".
At a very minimum make
http://msgplus.net/ and
http://msgplus.net/download.php redirect to msgpluslive.net... because those URLs are mentioned
everywhere on the net as
the place to get the lastest Plus! version.
A banner thing may sound nice, but look at IRC... we made a freaking huge colored topic with bold and everything... people just don't read, they just instantly click on download and expect that will give them the latest version.
