No, we do not sell or share your email address with anyone. The only people who can see your email address are the administrators, and they will only look for it if there is something they must discuss (when the only other alternative is banning a user).
There are some emails that we will send you. For example, you will probably get an email telling you that I have replied to this topic. If you do not want to get such emails, you can turn off the email options in your user profile.
Our privacy statement is very simple. Like you, every single member on this forum is a volunteer (including every single moderator and administrator). We will not do anything that we would not want done to us.
