My guess is... that is total number of userID's that they have in their database.
You can be a member, but a non-paying member and still use the site -- not fully, but when discussing "members" they are looking at the border picture, not the declining paying members. There is no way DoG is over 700,000 paying members.
Most of the forums I have participated in within the past 8+ yrs... they are dying.
