Slovenia is a right and important place to begin, I think. Granted, I have no idea what the amiga means in that part of the world anymore, but just a few years ago it, and the surrounding countries, contained the largest amount of (visible) coders and (visible) users - to me, at least.
To conclude: unless something serious has happened, I think there will be plenty of interested people attending the show in Slovenia. But I will let you rest assured that I am from Denmark and really have no idea :-)
Sincerely,
