UPDATE (3 Mar 2018 @ 10:00pm PST): The AE Creations website is now up again. Thanks for your patience.
The AE Creations website is currently offline. The site is hosted on Sourceforge.net, which has undergone a recent datacenter move, and now there is word of a denial of service attack, affecting all project web sites, including AE Creations.
To download and install Clippings and Panic Button, head to the Mozilla Add-on pages for these add-ons. If you need help on them, browse or post to the AE Creations Help and Support Forums on Google Groups.
