I don't know if there's any way to edit your email address out of the post, but you might want to ask the board admins to either edit it out or let you edit yourself. There are four little icons at the bottom of each post -- the rightmost one says "Notify Moderator" when you point at it.
Nobody on here is going to cause any trouble but there are a lot of automated programs running around which scan web sites looking for email addresses to sell to junk email companies.
We normally send email addresses via PM (private message) rather than posting in the hope of getting less junk email. Not trying to scare you, I just hate spam
Congratulations on the new speakers, by the way. I have M60s as well and couldn't be happier with them.
