2500 ELO? Damn. Guys, that means someone from Warlight has earned his first GM norm!! CONGRATS LATNOX!!!!!
The requirements for becoming a Grandmaster are somewhat complex. A player must have attained an Elo rating of at least 2500 (although they need not maintain this level to obtain or keep the title). In addition, at least two favorable results (called norms) from a total of at least 27 games in tournaments involving other Grandmasters, including some from countries other than the applicant's, are usually required before FIDE will confer the title on a player. There are other milestones a player can achieve to get the title, such as winning the Women's World Championship, the World Junior Championship, or the World Senior Championship. Current regulations can be found in the FIDE Handbook
Now you just need to win the World Senior Championship, and you'll be Warlight's first Grandmaster!
