Thank you very much!
I do try to read the intruction manuals (so to speak) but there's always so much info when you join a place like this (and I'm also not good at social-media-ing.

Another thing I haven't been able to work out, if you don't mind another newbie question: I still haven't managed to change the default posting setting from private to public.
I have changed this X times in Settings but it doesn't take, so I still have to change it manually to public each time I post.
