yes and imagine this way: if we set up a event and say the date for it will be week or two from this day. Some may have spare time but some doesn't, they say after three weeks would be better or maybe after four. And even then when they sign in ( leaving people out who were willing to join but couldn't fit in anymore ) they might have suddenly something better to do. Its just a game of course, but Im not glad of this that we're making a event for players and they show their gratitude like this.
