OK. Before hit the bed, logged on from MacBook. Looked like though I had logged on earlier from MBA, it did not remember my log-in credentials on the browser. When tried logging in, first instance, it gave me a message to say "Could not log in" . It took a few minutes for me to figure out, I had omitted one letter in my email address in the log in field. I'd thought, why didn't it just say something like 'incorrect email address' ….?
When we do not hit any menu buttons above for text formatting, we can write posts in *Markdown* , I think like **this post** here.
