If I can't find it after a long time, I get frustrated and e-mail them for a hint. I just can't wade through the mass pf pages at some of the huge sites. I won a ten dollar gift certificate there once, and if you look through the old posts, there were some second place winners on the board.
I think the first few I did, there was a rule that it could be no more than six clicks from the frnot page, but now some are just buried.
