Put a "button" on the Mercola.com web site, like the "Health Blog" button so that it could be "clicked" on to go to this forum.
Since it is a "paid" forum, you could have the "button" "grayed out" or not work if the email address of the patient on your web site does not match your email database of patients that are members of your NT forum group of paid patients.
It would make it easier to get to the NT forum, while on the Dr M web site. Of course we can always add the forum to our favorites list and get to it that way; but if it was on your web site it might generate some new patients? Just a thought.
Have a Great Day & Thanks,
