Someone mentioned to me there is a conflict when on the one hand I ask students to be independent thinkers, and on the other hand I only allow the students to post their submissions publically after I've OK them.
I realize I should've been more clear about that.
When I am checking a submission, I just want to make sure the students responded to one of the topics and not some other ones, or mix up all three together. I want to watch out for things against the forum's rules, such as inappropriate words or discussions of warez. I also want to make sure each person is only submitting one piece for each topic. That's all.
It's a mere formality. I will not block submissions because I disagree with them or don't like them.
I may suggest some changes on grammars and comment on whether the writing make logical sense or not, but I will still OK a submission if those suggestions are not followed.
The latter part I might take more seriously because this is a great chance to help the students improve their writing skills. I might just let every submission with grammar and other sorts of mistakes get publiched, and setup a formal process where I ask some FIRST mentors to help review the writings and give the students helpful suggestions on how they can improve their writing. But I need to think more on that.
Again, the more submissions the better
