One more point I would like to add ...
In an ideal discussion site members should give space to others and not let minor misunderstandings or mistakes made by other members become major issues . When we complain to the moderators we have to take many things into account - first of all whether we are in the right , since no one is perfect.
Moderators on their part should take care to see that the complaints are valid , in fact make sure that the person who has complained has not done because he or she has some grudge against the member, which can easily happen with some members! It happened in the past and it may have happened again .But in the best interest of the site such things should never be encouraged. In fact I have always brought out my complaints if any on the open forum so that the other person has the opportunity to present his/her views , rather than go behind someones back and complain.
