Sorry, I cannot increase the number of players again but as it seems I can decrease it. Unfortunately I decreased it to 4 so I had to delete the game and set it up again. Now there should be enough space for everybody. If I would have known that Brat was a friend you I would not have kicked him.
But I didn't know and I had to kick several players as the open spots filled very fast. Nevertheless now there are enough slots open.
Thanks again Geoschmo for the fast help with setting up the game again!
