Hmmm how do you find out the posting date? sounds interesting..

Just go to the post and change the URL so it says https://steemd.com/... instead of https://steemit.com/... and you'll find the date at the top.

Since a couple of months, I've been using RSS and IFTTT to automatically save all dates, titles and links to my posts to a Google spreadsheet, so for those posts I can just refer to the spreadsheet, but it is useful for the posts I published before I had this system set up.

Btw, I remember you posting veeery similar learning...about your back issues..like one month ago.

Probably won't be the last time, lol. I may be a teacher, but when it comes to learning things myself... sometimes I need dozens of lessons before I finally get it :0)
