A)Scope sent message how to get notifications, but inadvertently it is off, and won't accept change

I put several new topics, and I'm confident there was nothing wrong in them, but only 2 are there
C) serves me right for not previewing, but can you get back to edit eg punctuation or typo?
D) is there a way to view your own replies? Is that what notification does?
E) will I never recover what I put down today and last night, as new post or as reply ? (Repeat, absolutely nothing that moderators would have wanted to block or remove. )
F) is for Finally. Finally, where should I request info on a gadget rumoured to exist?
It can be fixed to the car handbrake, so that weaker wrists can pull it up just as firmly as strong
PS. This is a brilliant site, thank you.
