Having been put off by the multi user dev environment in previous tests I was reluctant to use it in a 7.8 environment.

But there is a catch.
The trick is to get your Projects right to ‘Check-out’. But of course you get a chicken and egg situation. You need the rpd set-up first to create the projects!
I’ll let you figure that one out.
