(Also: Irt or irt)

1. An initialism for "In Reply To" to ensure that readers know to whom you are addressing in the Comments section of an online article since some web pages fail to insert this information automatically.

2. A useful abbreviation inserted as the leading entry of a/your comment followed by one, blank, character space and the name/moniker of a previous commenter to whom you are replying. Examples: IRT Bob Jones, Irt BillyBob, irt sillywilly.
