Decayenne closing for an indefinite period of time

Just before they closed, they posted the following msg once you were logged in :

"Farewell Decayenne

29th July 2010

There are some unfortunate news we have to announce today. Decayenne will shut its doors for an indefinite period of time. In the past few years the social media market has changed dramatically, making it increasingly difficult to maintain a private network like Decayenne. Hence, we have decided to refocus our resources on other company projects.

The website will remain online 2 more weeks, so you have the chance to save your information, messages and pictures. Please note, that after this date we will delete all of your personal data.

As we have invested many years of work and passion in Decayenne, it was a very difficult decision for us. Still, we are very thankful for your support and happy about the unforgettable events and new friends we have met along the way!

Sincerely, Your Decayenne Team"
The website now displays:

"We're sorry, but we shut down the website for an indefinite period of time and we cannot say yet when we are coming back. Just remember, we will always love you!
Thank you for your understanding."
