I think some people might sign your email up for **** and spam since you listed it here. Generally a bad idea, but at least it's not hotmail.
It's smarter to have people PM you through the forum.
Anyway, I'm guessing your email reply will contain the referral link that you can't post on the forum due to the filters. So your post might be seen as indirect advertising.
