Hey Banjaaran, Thanks for bringing this up from your end ... Even I have seen people answering only for the sake of credits and it should be stopped I guess ... Once it is seen that the question is answered in a correct manner, I don't feel there would be any need to answer it all over again ... If there is something to add to the answers also it's fine to give away the answer .... Hope people will take it to consideration and not continue doing it again ... Happy Travelling!!!
