StumblrUpon Going June 30 Immediate Action Needed to transfer

StumbleUpon is leaving.  They are going down June 30.  However, if you are posting there and go to the site they have a simple way to transfer to Mix.  It is a little more than a single click.  You must select at least three interests to join.  But it takes just a few minutes.  It must be done before StumbleUpon goes away or you will not transfer content all at once.  They do not allow commercial use, so if you have a selling website you might want to keep it from transferring.  You can select a partial transfer if you like.
