Okay, guys, I must confess I am very disappointed by most of you... amongst all the people who said they would come (not just that they could maybe come), only Kloug, cwxa99 and dleblanc343 with his friend showed up. The room was 113,93$ including taxes, and since I asked 10$ from all of the attendies I only recieved 40$, which means I paid a total of 73,93$ on my own for the room.
Now, bear in mind that I only made the reservation since we would be enough people. I for sure wouldn't have rented it last week if I knew we were to be 5 people, since it would have been 20$ per person. Now, all the people who commited to come are responsible for me renting the room, and hence paying the room fees. JSoriginal has already PMed me to apologize and has also followed me his part of the payment for the room. I expect everyone to understand that their commitment must be followed, and each person that did commit and didn't come should contact me to arrange things, may it be by a payment of some sort, or an arrangement for the next meet.
