Welcome to Amiga.org!
Great that you got Amiga Forever installed and working. As far as the Amiga goes for me, I just use OS 3.0 since that is the only version of the OS I used when I had my Amiga 1200. I do have OS 3.9 going, but I just miss the plain looking workbench that I was used to.
Have fun and enjoy computing when it rocked!
