Four-H Club – 4-H Club is preferred. Members are 4-H’ers.
free – Use free when the target audience is the military community, service members and family members. Free is easily understood and preferred when writing content for service and family members and service providers and should be used instead of no cost. However, when writing content for leaders pertaining to Military OneSource policy or the Military OneSource contract, use the term no cost. Facebook is the only exception to the rule. Due to its algorithms, use either no cost or a variation of “take advantage of your benefit.”
