It can never hurt. Establish an e-mail and phone list. Make the team roster available frequently. They are, but most of us are in the water to make friends also. To this end, it's important to keep the team roster up to date, and to make it available to everyone.
Many teams send out the roster quarterly or on another regular basis.
Also, make sure you have a policy about deleting names so the membership list doesn't get too unwieldy. Keep the mailing list up to date. Again, respect member's privacy. Don't make the roster available to the media without members' permission. Letting vendors use the list will probably make some people mad, so think carefully about that.
