Yes you can send him a Nikonians e-mail. Both of you are Silver members. What I do normally is send the e-mail, then in the I Want To Sell... forum, mention that you have sent he/her the e-mail. As far as I know, the only way a member can see if he/she has a Nikonian e-mail, is to check their My User Menu, then the e-mail tab. Hope this helps. Terry.
