I use Netscape's free e-mail service as my non-work e-mail account. When I started this morning, I couldn't send e-mail through Netscape's server. So I spent the morning modifying and deleting and restoring files, making things even worse, until I reached the conclusion that the problem was probably on Netscape's end. Then I spent the first part of the afternoon fixing the stuff I had broken. Now, having spent all that time, I still can't send e-mail through netscape's server. But at least it's in no worse shape than it was this morning.
Sigh... On the whole, not time well spent.
