SCU was a series of posts made here on this BBS by Jerry in WI, so you have to do a search to find them. When I have time I'm going to try and set up a page of direct links to them but for now you have to follow the steps Jerry posted to find them. Here they are again.
1) click on "search" (at top of message index)
2) on the search page, click on "Posted between 8 July 2001 & ...February 2002" (or you only go back to search the last two weeks)
3) on that page click on "messages containing... ALL.. of the following key words>"
4) type in "SCU" after that part
5) hit "search"
