The AE Creations website is currently unavailable due to a server outage on SourceForge.net, the website host. This outage has been going on since 17 July.
In the meantime, the minimalistic fallback site, hosted on GitHub, is available for those who seek the comfort of visiting a website with the AE Creations name. The Mozilla Add-ons pages for Clippings, Panic Button, Send Tab URLs and Delicious Post are available as well.
Updated 2015-07-22: The website is now up and running again.
