I'm not for message privately, I think it night be hard to keep it safe.
I think there should be a level below sophie ms and official moderators, peers who can let's say sign up to help with moderation.
Then if someone gets upset, or there is something offensive said, that person would be able to email the users affected.
It would be more meaningful I think, then getting an email from an anonymous "moderator" generically saying to hope Ur OK, because that email is, like or not, from someone above u, a clinician, and its not so trauma sensitive that they send these emails.
It still feels like an act of power of clinical over the user.
I think maybe some users should be able to lightly moderate, including emailing users in distress or those maybe getting lost in the forums or accidentally braking the rules.
