Before MobileMe there was .Mac, and before there was iWeb, there was .Mac HomePage. Well, good thing the latter has been replaced 'cause Apple is officially declaring them EOL (end of life) come July 7. After that date, whatever is there will remain there forever (or until Apple gets tired of it and yanks them down). So get with converting to iWeb or rolling yourself something custom.

Dear MobileMe member:
On July 7, 2009, the .Mac HomePage web application will be discontinued. As of this date, you will no longer be able to create new pages or edit existing pages using HomePage. Any pages you've already published will remain live at their current web address for as long as you like. If you need to make changes to your existing pages, please do so before July 7.
Instead of HomePage, we recommend the other sharing features of your MobileMe membership. With MobileMe Gallery, you can share photos online directly from iPhoto or the web application at www.me.com. And using iWeb on your Mac, you can create custom websites and blogs and publish them to MobileMe.
We apologize for any inconvenience this change may cause. For more information, please read this FAQ. And thank you for being a MobileMe member.
The MobileMe Team
