A good place for your members to discuss other stocks is on the Off Topic Forum. I ask my Hub members to post there when they want to recommend another stock. Fortunately for us, Agoracom has provided this excellent resource for such posts as well as the opportunity to send Private Messages to other members. Negative opinions are o.k. if they are presented in a respectful and fact based manner. IMHO both outright pumping as well as outright bashing should be avoided.
