Pikatrain pointed out that, through an oversight, margin discussions weren’t explicitly banned in the board rules. That oversight has been corrected :
No option trading discussions, or other discussions of using leverage, such as margins. (A recent poster described losing all of his 50% plus year to date gain, and two thirds of his account balance, on one 20%-25% move that he had bet heavily against using extreme margin leverage. That’s not investing, it’s gambling, as should be evident to everyone!)
Best,
Saul
