They will come just as they were originally sent. I thought it was worth answering. For this list the answer is no. It costs nothing for you to participate in the list. They do charge a small yearly member fee for members of their organization.
Every member is entitled to operate two lists.
They charged nothing for this and did not require any Maiser listowner to join in order to operate their lists. Since the choices were fold the list, move to RootsWeb or find another location, they could easily have charged a fee. I observed how they operated for some time and decided to join. They do a top-notch job and have done quite a bit of hardware updating to handle the 2000 or so Maiser lists they picked up. I encourage list members to check it out.
