Keep it current. Keep it interesting. People will read the bulletin board if it is current. More interesting and faster delivery of information. Feature membership diversity.
People are interested in other people.
Use the diversity of your club to your advantage in creating interest. Make sure the Board has some training in what questions they can answer and which ones have to go directly to the coach. Get your name all over town, and use the thank you's with your own club members. Be very generous in saying thank you. Some will end up framed on walls for all to see.
