I agree with Taye. No one ever likes to hear that they're wrong about anything. A welcome and a mention of the dreaducation page is plenty for newcomers that haven't posted anything yet other than their profile. Not a "Welcome...but you did it wrong." Even if it's sincerely to help them, it does not come off that way. Sometimes I avoid commenting on posts from newer people that have crocheted or waxed because I know they're going to get blasted and I don't want to overwhelm them further. They'll figure it out soon enough and will ask questions when they're ready to hear the answers. Thanks for the post Baba!
