Yahoo is closing down Geocities later this summer. Exactly what that means isn't altogether clear at this point. As far as I can ascertain it means that anyone with a free website has to upgrade to a pay plan or be wiped off the face of the internet. Time will tell.
I'm a bit sad at the news really, I have never been that computer savvy, but I found Geocities realtively easy to use and I built several nice looking sites using it.
