This template is not blank, it adds a little icon in the top-right corner. See?
When hovered over, that icon shows your IRC nickname, and is also a link to WP:IRC. It is inspired by a topicon originally made by User:A930913.
This template adds your username to Category:Wikipedians who use IRC.
Place {{User:FlightTime/IRC TI}} anywhere on your user page.
This icon is based on {{Top icon}}
