Over 30 percent of Limbo’s mobile social community members are active each month. Earlier this month, Limbo added location features to its social networking tools, which enable members to set what activity they’re doing, where they are, and who they’re with, through mobile phone applications, text messages, Internet or mobile web.

Limbo also added a group messaging tool which allows members to send a text message to multiple friends who can then reply to the entire group, further enhancing the interaction of the community. Limbo’s community is open to all members, regardless of carrier or mobile phone model.

“Limbo’s tremendous growth over the past six months is a direct result of our continued commitment to grow our mobile entertainment applications that add value for members,” said Jonathon Linner, CEO of Limbo. “Limbo members are actively engaged in the Limbo community and have strong relationships with other members and the products advertised.”
