Hi, I appreciated you reminding us about oil symbolizing the presence of the Holy Spirit and the healing aspect. To answer your question about the "R" look on the front page of the forum. Right under the Title of the forum are the options "R"-recommended reading, R/N- recommended for the newsletter, and BSA- bright star award . Click on the "R" and you will see a list of recommended messages regarding oil pulling. This is standard for all the Support Forums .
Edit-Actually, now all you have to do is click on the words recommended messages to access the "R"s.
