Peter Toft and I are in the process of preparing Emacsforum 2011 with some help by Troels Henriksen (at DIKU) and Keld Simonsen (from KLID). The program is almost ready for publication, so I will not say too much - but there will be something for scientists and developers. Even our Evil Twin will be represented.
The mini-conference takes place 12th November 2011 at DIKU. The is no conference fee - and there will be no benifits.
If you are using Emacs (and even XEmacs) and live in the Copenhagen area, Emacsforum is a good place to meet fellow users.
