Thank you Werner...It is really so easy...
How couldn't I see this...Sorry for bothering you ...

BTW, I don't quite get it what you mean by
I for myself did this: within the line

Welcome (my name)" =>
Settings =>
General Settings =>
Messaging & Notification =>
Default Thread Subscription Mode =>
Instantly, using email
Please foregive me if it's another silly question!
Greetings
