Hi CA3LE, thanks for your responses.
No, I've just discovered the fantastic(ish) testmy.net
I did try some shorter initial tests without signing up, which, ironically, worked great 🤣
I only set up one username AFAIK (I used only one of my email addys throughout, starting with EPS -if you can see that) although the setup sent me around in circles repeatedly, not liking my attempts at a PSWD... using Uc, Lc, a No. & a special character.
I'm an IT teacher, formerly an IT technician, so like to think 😬 I'm reasonably competent in such things... But an ready & willing to b schooled if it's me that's fecked up rather than the site's database 👍
