Once again, thank you everyone.? I have gotten a lot of valuable information from everyone.
Thank you Christos for that very detailed explanation.? I will try it out.
First, the answer to my troubles, at least for the email address I managed to subscribe today, was to clear out the cookies.? I chose Google Chrome as my "testing" browser and use MS Edge as my "live" browser.
I don't use Google Chrome for anything else, so I don't have to worry about deleting cookies and other info for other websites.
It worked very simply, never shipped me to the groups.io website, which is what I am looking for.? This is for users who strictly want to deal with the email address.
I will review all of your comments again to see whatever other nuggets I can find.
Thank you
Darlene
