text: how can we check whether the same person is asking questions &  answering them using different user id-ies ? i think that in order to gain points many memebers are asking qustions as well as submitting answers for them, by using various user id-ies ! any comnets on this view ? this is certainly possible.  i beleive that there is no way for users like you and me to find out, but i am sure that the development team can tell if they are looking.  that would require that soemone suspects a person of this subterfuge and reports them.
