I sent you a method of using legacy Blogger. Via email,. The email you list in your About Me section. Do you have a newer email?
The mail address is still valid but so old I have no idea what the password is so the only place I read it is on my iphone 4 which is also very very old in tech terms. My computer dates back to 2012 the phone was bought off ebay shortly after the computer entered the house.Pam laughs at me because I don't use a cloud program to remember all my passwords like she does. I write them down in a little black book that finally filled up this week. I have to start another book to write stuff down in so I can spend hours looking for the page I need.
