Okay, who else doesn't use the Document Exchange program thing just for sending beta-reading documents?

I do use it for sending Documents that I have beta-read, but I also use it for so much more. :) like,

-sending a chapter of a collab I'm doing with another writer back and forth until is is a model of perfection and she posts it.

-send documents that I will never post on ff to my ff フレンズ to read if they are bored.

-send ランダム spammish ジャンク to my ff friends. They are usually colorful. The ジャンク I mean.

-send birthday または holiday 'cards' to them. I just send them text art and holiday wishes and stuff through it.

-etc.

So I actually do not use it for much beta-reading...i did not know it was just solely for that. Is it? What do あなた think?
