Yes, mailman's search service which DreamHost administers isn't working, and we don't even have access to our mailman data.  We've contacted DreamHost many times seeking a resolution.  This is just one more reason why we are in the process of moving everything to our own KVM servers.  The migration involves plenty of work, but it will be brought to fruition .. note to Jonathan, myself, volunteer B!B!E! system administrator.

Here's one:

I, and my heirs, in consideration of my participation with "CBS NAME" hereby release "CBS NAME", its officers, directors and agents, and any other people officially connected with this organization, from any and all liability for damage to or loss of personal property, sickness, or injury from whatever source, legal entanglements, imprisonment, death, or loss of money, which might occur while participating in said event/activity/class. Specifically, I release "CBS NAME" from any liability or responsibility for my personal well-being, condition of tools and equipment provided and produced thereof, including, but not limited to, bicycles and modes of transportation produced by participants. "CBS NAME" provides a working,mechanical environment and I am aware of the risks of participation. I hereby state that I am in sufficient physical condition to accept a rigorous level of physical activity and exertion, as is sometimes the case when working in a mechanical environment. I understand that participation in this program is strictly voluntary and I freely chose to participate. I understand "CBS NAME" does not provide medical coverage for me. I verify that I will be responsible for any medical costs I incur as a result of my participation.

Also, look at the League of American Bicyclist waiver - https://appsrv4.amerspec.com/dbweb/f?p=144:2:3582501108255189 , and even consider joining their insurance program - https://www.bikeleague.org/content/insurance-clubs-and-organizations

As Kevin points out, you should run any waiver you plan to use by a legal mind.  Additionally, ask your Insurance provider because they sometimes provide boilerplate waivers like LAB's insurer.
