I think it'd be nice if the author could reply to comments directly. I've been messaging everyone who commented on my story individually and I think it'd be easier if I could just reply to the comments themselves. And this way other people would be able to see my replies to the comments which I think would be good.
Oh xD I looked to see if there were any other threads about it but couldn't find anything! Must have missed that one that was only posted 5 days ago somehow!
It's in the "closed" section :)
