I see now what is happening.
I have been expecting an email alert not monitoring the alerts shown on the upper menu bar.
Because I have all alerts turned on in my account settings these with @usernames are generating alerts but they basically getting lost in the other alert noise.
That was a my assumption and the reason for the test use of it in the first post of the thread
21 minutes but no alert as of yet.
Checked my account settings and have all alerts active.
Maybe it doesn’t work if you self post it.
There is a huge vocabulary of internet acronyms.
You can google search for most with great success and there are a few websites specific to internet acronymns as well.
Happy netting.
