No I haven't tried experimenting yet in case
I screw things up.
The only thing you're going to screw up is your own ability to use PPRuNe.... so I'd humbly suggest to get your lab coat on and get on with your experimenting.
Work methodically, making notes of what you turn off at each stage, then you have a regression plan if you mess up.
It's only a simple forum application, so if you can read posts and write posts, then it's still working. So shouldn't take you long to test.
