He is best known for creating a website, The Rantings of Lum The Mad, a pioneer blog, which existed from 1998 to 2001, when Jennings was hired by MMO developer Mythic Entertainment,[1] where he remained until 2006.
Jennings, whose primary career was as a database programmer, became a respected critic of UO, as he posted detailed critiques of the game.
Jennings's strong views on "macroing" – the practice of automating aspects of the game, effectively making it easier – made him very popular with some UO players.
Other issues he covered included "squatting" by large guilds, class balance, real-money trading, server lag, "raiding" as an end-game, and the later expansions' lack of finished and working content.
Instead of the usual review article for World War II Online, he posted a long, profane and amusing chatlog of him testing the game offline, in which he proclaimed, "I WILL TAXI TO VICTORY!
[citation needed] Jennings' website attracted many well-known MMORPG staff and developers who took part in discussions on the forums.
In 2001, when Jennings lost his job due to the dot-com crash, he was hired as a database programmer by Jacobs' company, Mythic Entertainment, makers of Dark Age of Camelot.
Also in 2001, Jennings started a new blog, Broken Toys,[5] which he infrequently updates about random subjects sometimes but not always relating to online gaming.
On February 17, 2006, Jennings left Mythic and began working at another MMO company, NCsoft in Austin, Texas.
