Check your spam filter too to see if the emails are going there.
You can always visit the board without receiving that daily email. I seldom use the link in the email. Instead, I save the link to Main and Pictures (the two areas I visit most frequently) in my favorites. I like to see the board sorted by time of posting, so I sorted each forum that way before saving them to favorites. All you get in the email is the link to the most active topics, and sometimes what is most active may not be what is most interesting to you!
