I suppose there is no way to see when or what comment earned me jeers either. I have negative points

If a moderator looks back at my posts, I don't think I've posted anything ridiculous (especially considering some of the misguided suggestions I've seen young cheerleaders offering each other on these boards). I'm pretty sure someone disagreed with a suggestion I made to a flyer suffering from bruised ankles (I told her to loosely ACE wrap it to add some cushion until her back spot loosened the death grip), but I can't imagine that earning me a jeer.
As someone else said, it's a little childish for someone in their mid twenties, but it hurts my feelings. I feel like I've gone out of my way to educate myself as a coach, and for my peers to judge me as uneducated/unsafe/unwise... Maybe I'll just have to look elsewhere for my sense of self worth.
