GaymerX managed two conventions, but the third round is currently on Kickstarter, trying to raise funds for another convention focused on inclusiveness and support of all different types of gamers. That goal is being helped significantly by a big name in online gaming: Blizzard Entertainment.
The Kickstarter site for the convention lists the World of Warcraft developer as pledging "over $10,000" to making the convention a reality. There are still 23 days for the project to reach its funding goal, but that kind of money certainly helps kick a project along. If you're interested in donating yourself, the convention will be in the Bay Area of California in either November or December of 2015.
