BalCCon already has an assembly area which basically is just a larger space within the conference center. So booths would consist of a table and some decoration, just like at other conferences. We could also think of offering some small merchandise, especially if we were more than 2 persons.
Would you be in? Then I can ask for a place, send the stuff to Serbia, and announce it.
I'm not much of a booth person to be honest :) And of it's just the two of us, we would probably miss most of the Congress and the opportunity to engage with people on sessions and workshops.
Maybe next we can get organized earlier. I've heard only good things BalCCon that it would be nice to have a more formal presence there.
