The Vibe & the Golden Rule : Read the vibe of the room when you enter. Read the title and the topic. Treat others as you would like others to treat you 
Be KIND; Try to really listen with care and respond with kindness.
Generosity & Respect : Be GENEROUS ; Share what you know or have experienced, it can help someone. BUT No pitching or sales. This is not the place to promote your services, products, or projects (unless asked by moderators)
To respond or not to respond : If you feel it is difficult to respond constructively or with kindness , just don’t say anything at all.
