i agree with dr kergel, it may be, but even if it is, he has not started any trouble, so let it be until he either needs help hten help, or if he starts a problem then deal with it, don't forget this is america, where you are innocent until proven guilty
besides, i am sure the sharks saw it and will be checking into it and keeping an eye on things in the mean time
but also, i gotta wonder how this french speaker signed on and responded to a couple of peopple if they don't know english, yes you can use translators, but why not respond in english with it(although sometimes not 100% clear, at least ti would help some)
