I have uploaded memoir.tar.gz to UK incoming. Please use this toreplace the current macros/latex/contrib/memoir. The distribution is under the LPPL.
From the README Memoir is a flexible class for typesetting general fiction, non-fiction and mathematical works as books, reports, articles or manuscripts. Documents can use 9, 10, 11, 12, 14 or 17pt as the normal font. Many methods are provided to help you create your particular design.
