- This page refers to the storyline that ran in 2007. For comic #1337, see 1337: Hack.
- This series was released on 5 consecutive days (Monday-Friday) and not over the usual Monday/Wednesday/Friday schedule.
- The title 1337 is "L-eet", or "elite", using the Leet alphabet, a coding system used primarily on the Internet (and on early text messaging system), meant to provide a bit of obfuscation to plain text, both to make it harder to read and to show off in a creative way using in-group jargon.
- This comic series is aimed at elite hackers and programmers.
