There is sticky at the top of this forum from Spark outlining the rules for passarounds. The most recently added rule is the 6 month membership requirement. Simply put, if you haven't been a member for 6 months you can't participate. You can run or host a passaround regardless of membership time.
Those of you running passarounds, please follow this rule. I'm seeing this rule being broken and we all need to follow it.
Thanks and don't hesitate to contact me if you have any questions.
