This is the body of a thread sent to the team leaders-
We wanted to let you know about a small feature that launched today.
On every SparkMail message you will now see a "Block This User" link on the right side of the page. After blocking, you can click the "Block List" button on you main SparkMail page to see everyone you have blocked, and be able to un-block members.
Once you have blocked another member, if they try to send you a message they will see a general error saying you are not receiving SparkMails.
Hopefully this feature won't need to be used very often, but it is there just in case. Also, if you get an inappropriate SparkMail, we still encourage you to click the "Report" button at the bottom of the message so that our staff can look into it further.
PS This does not block someone from your Sparkpage.
