I think that there are a few months before the old site goes away, but the official site for AMFPHP has been moved to http://www.amf-php.org/ instead of the old http://www.5etdemi.com/ site. The link below has some details.
Well I’ve fully made the transition to grad student and will be closing the site once the domain expires, which is in May. My new email is patrick DOT mineault AT gmail DOT com, and I’m on Facebook if you ever need me.
P.S. I can furnish FTP details and a MySQL dump if someone wants to mirror the blog archives.
A long time acquaintance, Wade Arnold, has stepped up to replace me as lead of amfphp. I have full confidence in Wade, who is very knowledgeable of the engine and has a large team of in-house developers to back him up. He has already worked on enhancements to the 1.9 version, which are going to be included in the 2.0
It would probably be a good idea to update the links on the AMFPHP project page and in any files in the project download.
