If the question is "What do you get if you multiply by seven the total number of paying members who have EDIG boardmarked."
I have no idea how many of those 6 have it boardmarked out of morbid curiosity or how many actively post about the stock. Would be easy enough to check, but I don't care enough to.
And you're right that there are plenty of paid subscribers on the site with no bookmarks and no posts.
Not sure what this discussion is about since I wandered into it while it was already in progress, but I wanted to point out that to say "No EDIGgers are subscribers" would be an incorrect statement as would "A substantial number of EDIGgers are subscribers."
