Well, Mr Sauldie, that was just great, thank you very much!!!
I'll probably start with Google, I'm still unsure about facebook because there was a warning from the Federal Constitutional Court about facebook (do you know it?).
In any case, social media cannot be neglected.
Do you have a newsletter?
I would like to register for it.
And I will recommend you anyway:)
Best regards from Mainz
