Contribution limit for a Health Savings Account?

Opened HDHP with an HSA on Oct. 1 2010. Simultaneously terminated the HMO that we had for the past several years (much higher premium.) The HDHP with HSA is a family plan. I'm self employed. My wife is self employed. Neither is covered by any other health plan. We're 42 and 39. Have three small kids. I think the answer is $6150.00.
