For some time, the only one (edit: not anymore - now, Glen can too) with any kind of moderator powers on the main forums, Max can move threads between forums to ensure that they stay on topic.
In November 2007, he decided to retire from AH.com, wanting to do spend more time about other things than AH.com, and thinking it's better to quit while it's still good and you don't suck yet. He still looked in about once per week. Sometimes less, sometimes more.
Pet peeve: Doesn't like how Wikipedia nowadays is nicknamed “the genocide” on AH.com.
He is an admin/bureaucrat at the althist fandom wiki (formerly Wikia). Sorry folks, but a wiki gives you possibilities a plain forum doesn't have. And a MediaWiki gives even more than this one, so sorry too.
Jaredia: Humanity on a tilted Earth
Hitler's Mediterranean Strategy - Completed.
The Chaos Timeline - Completed. Max's magnum opus, showcasing with great detail eight centuries of a world where Genghis Khan died early and never forged his continent-spanning (if short-lived) empire. The consequences for world history are massive.
How many Sixes does Adolf Nazi have to Roll? - About the eternal question of whether Nazi Germany could've won World War 2 in a half-way realistic way. Still not solved.
In November 2007, he was nominated as Patron Saint of Unfortunate Thread Juxtapositions (UTJs). Reason: At this time, his Chaos TL was on top of the T&S forum, and its shortened title (Chaos TL - A world without…) is very useful for UTJs. Unfortunately, only together with threads from the Books & Media forum, which gave us lots of repetitions of UTJs of the form “Chaos TL - A world without… Map Thread III”. Unless one takes a UTJ from New Posts or Day's Posts .
He has a knack for finding obscure AH in places where you wouldn't have suspected it:
“In my Chaos TL…”
“After the election of two Roman kings at the same time in 1256, the HRE got splintered into some hundred political entities, which kept Germany divided for centuries.”
“In 1939, Germany was practically broke because Hitler had spent all the money for armaments and HAD to go to war, or declare bankruptcy. (And if it wasn't for the Austrian and Czech gold reserves, they'd already have to do so in 1938.)”
(Starting threads about obscure AH books) “Did anyone but me read this?”
He lent his name to the character Ixa'em in Chris' story “The Otherworld War”. He also appears as a villain in "I f***cking hate Grey Wolf!".
Max Sinister makes an appearance in the AH.com The Series episode “DON'T MENTION THE PORN” as part of the Germans. After appearing in later episodes, he was eventually killed by the Administratum of Bankind in the episode THE ULTIMATE SHOWDOWN.
Has strong wiki-fu, which he uses in secretive ways, across the entire expanse of this great 'pedia. Although Petike some time later overtook him, never to look back.
