I think that if somebody thinks that an user (or some users) systematically incite him is better to say his name (or their names) and see where is the problem. GKO is for fun and the problems can be talking solved. Too many problems we have in real life, which sometimes want to escape, to also have bad feeling about what we used to escape.
How CarlosT explains it always were like this, but MathewsPateras have is right, the manual should explain these important details. Many of them are in various posts in the forum. There's a post started by Litmann, in the General Discussion, called "Questions and Answers", that is a great job, and with important questions solved there. I hope soon will be in manual too!
