A search in the Everything forum for the author's username, "void" (aka "David"), yields his last forum post dated Dec 6, 2011.
Per one of the most active Everything forum users ("therube"), registration in the forum seems to be closed, with the last user to register being on Apr 7, 2012; but there doesn't seem to be any official announcement about closing the registrations. I have attempted several times to find a way to register and cannot find a link to do so anywhere, nor any option to contact anyone without being registered. (If anyone here at DC is already registered in the Everything forum, maybe you can see more than an unregistered visitor can see. (?)
Changing the login URL (http://forum.voidtoo...m/ucp.php?mode=login
) to http://forum.voidtoo...cp.php?mode=register
yields a page that says, "Creating a new account is currently not possible." (Thought it was worth a shot in case the links were simply missing or messed up, but the function might still be available... ...but no such luck.)
From reading all the threads about the stalled development, I get the impression that no one in the forum knows what has happened to David Carpenter or how to contact him. I hope he's OK and will resurface sooner or later.
BTW, AFAIK, the last version posted is v126.96.36.1992 (Nov 29, 2009) mentioned above, and described Nov 21, 2011 by David as the most stable version (http://forum.voidtoo...288&p=4376#p4376
) just a couple weeks before his last post on Dec 6, 2011. (I originally couldn't find a link to v188.8.131.522a after I noticed it mentioned in a different thread, so I just tried modifying the URL for v184.108.40.2061a and was able to download v220.127.116.112a. But I tried additional modifications of the download URL with later iterations of the versioning schema and came up with nothing.)
Regarding the "alpha" designation, it seems Everything was being pretty actively developed up until v18.104.22.1682a, with v22.214.171.1242a on Oct 23 2009, v126.96.36.1995a and v188.8.131.526a both on Nov 19 2009, and v184.108.40.2061a on Nov 24, 2009, then stalling after v220.127.116.112a on Nov 29, 2009.
Nearly 2 years later, on Nov 25, 2011, David indicated "I still have much to implement before the next release" (http://forum.voidtoo...453&p=4382#p4382
). It's already a dynamite program, and I hope we'll all get to see and enjoy the next release at some point.
