Replying to an email almost 1 year old. I've lost archive-to-subtree functionality recently and don't know how to get it back w/ the recent Org code changes. While searching I found this old thread where Mark & Bastien suggest I'd need to sign off on someone using some code I pasted. I got that code from elsewhere, and only did minor customizations. In my original email I link to where I got the code from (
https://lists.gnu.org/archive/html/emacs-orgmode/2014-08/msg00109.html ). I don't think I have the rights to sign off on this, but sure, you can use what I pasted and my customizations. I've signed the FSF documents already, a long time ago. It seems like archive-to-subtree should be a core functionality, and if someone were to get that working again I'd be happy to test and use it.
-k.
