I would say 50-100 words, because that is not a hard thing to do. If a person hasn't written a long assignment, then tell them how to improve for the next time. And what they did well. It is feedback to the work they did and what you think would be better for the next time.

This button is already there, just not on phone.

The thing is... that individual posts can be deleted, so I don't know why the entire topic was deleted and not just the replies.

I would think it is the leader's responsibility to inform his/her team members if a page has been changed in any specific way.

I would rather think a select all button, because else you might accidently delete an important owl

Either make another account or talk to the Minister on the site.
