I must agree that
jb's explanations are very logical and sensemaking.
I also agree that the
T-Com is already occupied by the "Deutsche Telekom" and thus that I call the commander this way
I don't rememeber what was exactly the reason ("Total Anihilation" or "Mr. T") that associated this word to the Commander in my mind with these letters. (Maybe it was an advertisement for the Deutsche Telekom at all

). Just couldn't resist to vote for that
However will people "abbreviate" the name it doesn't matter as long everyone knows what are you talking about.
I also came to this Ill abbreviation.
Windows-
Total
Commander
With all respect. As a memorial... But never try to use it
Hmm... Maybe the abbreviations are not so good at all
And maybe the neutral all purpose word
Commander will just do the thing. But TC is TC. Just real...
