I would like visitors to see only entries filed in the last x hours. To see earlier posts, I'd like them to have to go to the archive for the particular day they're interested in.
For example, I've just filed a surf report for this morning in Sydney. At 0200 tomorrow morning I would like that report to be available only by clicking on the link to the archive. This means that if there are no posts on a particular day, visitors will see no entries on the home page. From a visitor's perspective the home page is wiped at 0200 every day and therefore if it's on the home page, it's no more than 18 hours old.
Again, thanks for your advice!
