Pete, I assume you’re an advanced user. Your activities here, if nothing else, show that.
What I do is not witchcraft. Everything I know I’ve learned by researching the WWW and trying it out on devices. My maxim is: theory is important, practice is life. So what I can do, anyone else can learn. I’m also learning every day. And that gives me much more pleasure than “100 years ago” at school :))
I only advise those users who know what they are doing to act on a system level. Please do not misunderstand this statement. It is not meant to discriminate against anyone. However, working at system level involves various risks from which the normal user should remain protected.
You will receive a PM from me today.
Kind regards and stay healthy and safe.
