We expected a small group, but in the end had 9 people. Not bad for Emacs Berlin :)
There was a suggestion to develop a function that could generically find and close the last open delimiter, and several guys set off working on that.
We had someone who wants to use Emacs to write a book. He used word before, now uses LaTeX, is looking at ConTeXt, and is generally sold on Emacs, although a few small annoyances remain.
We also had a long time vimmer visiting and asking many questions.
