I have used Krita to edit 1-2 page PDFs, but it’s clunky as each page is its own layer. If you’re looking for something that lets you add notes to an entire book or something… probably not useful.

It’s good to be paranoid, but for years I have had periodic sign-ups for lists I never wanted, services I never asked for, medical appointments and plane ticket reservations(!) I didn’t make … you name it.

All because I was an early gmail invitee, so my account is just ‘firstinitiallastname@gmail.com’ (with no ‘123’, or other decorations) – I was the FIRST. And I’ll be damned if I give it up!

So, so many people with my first initial and surname forget to add whatever crap they added to their signup after they must have gotten the error message at sign-up that told them ‘sorry, but firstname.lastname@gmail.com is already taken’ and they then forget whatever they added, and keep using my email address when they register for whatever crap they do. So bloody annoying.

I’ve taken to just logging into the numerous sites they helpfully send me registration links for, and if there’s a profile section I may (if I’m feeling cranky) set their profile photo and bio to unsavoury things, before locking the account. If I’m not feeling cranky I just unsubscribe/delete the account.

… for now.
