You can find a copy of the reservation form
here.
[ For the less technically experienced, you have a couple of options when you go to the form - 1) hit "File / Page setup" at the top of your Internet browser, then find a magnification that makes it fit onto the paper (~60%?), then print it, or 2) "right click" on the photo of the form, and "Save Image" as a photo on to your own computer -- then you can print it out from there, with the same magnifcation adjustments.
When I sent mine in, I noted on the form that I was part of the RBENT group, but that the reservation was only for myself -- Paul ]
