MessengerGeek with old version browser?

Is it possible to log in to the site with Netscape or Internet Explorer 4,5,6,7,8 ?

I’m afraid not. I haven’t tested all of these, but with IE, I believe you’ll need at least IE10 to even see more than a blank page.

There is a bit of a workaround if you need to view a thread on these browsers, you can append /print to any MG links and that will work in some older versions as the print page is rendered more simply. For instance, this thread would be, Not the best, but better than nothing if you need it and will work on any forum that uses Discourse.
