Jim Greer is stepping down as Kongregate's CEO, he announced in a forum post on the indie game portal's website. His sister Emily Greer will become the site's CEO, and Jim will stay with the site "half time" while also launching a non-profit political action group, according to Gamasutra. The change will go into effect on February 28.

Kongregate is host to thousands of games, both downloadable and browser-based, and also has its own in-house game development team. The gaming portal was acquired by GameStop in July 2010. GameStop established a $10 million mobile game fund for Kongregate earlier this month.
