I just got an e-mail from Yahoo informing me that its Mash social network is going kaputski:

Dear Yahoo! Mash member,

Thank you for trying out our Mash Beta service. We hope you had fun with it.

Please note that we will shut down Mash on September 29, 2008. As a result, your current profile on Mash will no longer be available. We strongly recommend that you return to http://mash.yahoo.com and copy the content that you wish to save onto a separate document.

For a list of FAQs, please refer to the Mash Help Page.

Thanks for trying out Mash!

Here’s the Mash FAQ page. Mash is/was the social network that allowed you to go in and edit your friends’ profiles, or at least turn off any gaudy designs they came up with. I reviewed Mash for Wired.com in September of 2007 when it was an invitation-only beta — it didn’t even last a year.
