This may not have been clear: I wasn't asking anyone to commit it *before*
the page goes up.  I was asking for someone to make a *commitment* to
commit a pointer after the page goes up.  I'm not going to put the time
into making the page and still have people asking the same question for
the millionth time because few know about the page.  Heck, part of the
reason I'm making the page is to save myself the annoyance of seeing the
same questions every day.  It's best for all involved for the page to be
prominent (as in, mentioned in the LOR warning).

Brian Feldman has now made the commitment.  Once I put up a decent page,
he'll commit the pointer.  If you'd like to help, let me know.
