Didn’t refresh the page before I posted that. I see it now. Thanks!

OK. Now I have it installed. I don’t see where I make the template groups and hosts or define groups or hosts as templates and make those associations.

I am looking to add the persistent groups plugin to my install of 1.5. I have found some forum posts about persistent groups but can’t find instructions on how to install it.
