I got a Powermac G5 lately and have been wanting to use MSN on it.
I had asked this question on the Discord ages ago, and somebody helped me out then, but it's not like I can go back and read what they told me again...

I remember it had something to do with changing your hosts file, but beyond that I forget what you're supposed to put there. I imagine it's just the Escargot server though.
If anybody remembers what to do, please help me. 
Thanks!
