Luke Drelick
Luke Drelick (currently known as djtiesto) has been a controversial figure throughout MegaZeux history. Since his days of trolling on mWorld under various different pseudonyms (usually named after Garage artists, a trademark that made him easily identifiable), he was in fairly constant conflict with the community administration. This came to a head about a year after the creation of DigitalMZX (during which time he used the handle SEGA), when he was "permanently" banned from the forums in September 2001 for repeated infractions against the ToS and a general feeling by the administration that he was only around to cause problems for his own enjoyment. This led to complaints by many of his friends at the time, as well as some attempted ban-evasion and raids.
In 2004, well after the furor had settled down, Drelick contacted the admins and dropped a hint that he wanted to be allowed back in, if it were considered acceptable. After some discussion, the admins allowed him to register a new account on a provisional, probationary basis. Since then, Drelick has been true to his word in demonstrating his willingness to cooperate with DMZX policies, and has actually become a respected member of the community once more.
Luke Drelick is also one of the more prolific MZXers in history, especially in his early days. He created several complete games of considerable length, the most famous of which is probably Engine. Since his return to the community, he released a special edition of Engine, and has been working on a similar treatment for Kikan, another of his older games.
