constructive criticism is so different than malicious criticism. I agree that one way to stay out of the later is to avoid offering unsolicited critique.
There is talk in another thread about creating a specific board just for gathering constructive criticism. I like the idea. That way, those that want it can get it without the ones offering it feeling or getting criticized for offering it!
Also keeps the integrity of the main boards as a supportive cheerleading community.
Does that make sense?
