I email Scott quite often as well, and I too have not received a reply from him. Don't worry though, Scott actually admits he not that computer savy, plus the fact that Anthrax(including Scott) is extremley busy right now finishing the new album and ironing out all the details with the new record contract they just signed. I have a couple of friends that have meet John, Frank, Charlie, and ofcourse Scott! In all cases, the members of Anthrax have been very happy, and glad to meet them. My friend Joel actually received what was left of some Barcardy 151 from Scott Ian's hands so I'm sure they would extend the same hand of friendship to you if you get a chance to meet them someday. Also ask yourself this question, "If you were in a popular band like Anthrax, do you think that you would have time to answer possibly hundreds of emails daily?" I'm sure that you may realize just how tuff that could be. I'm sure that Scott is happy to see the emails in his inbox(after all, we are the fans that keep them driving). Don't worry mang, maybe we'll both get a email inviting us to the release party!
Cheerz!
