Wow that is cool of you to do that. Can those be recorded if you can't watch them during play?
Yep, they are recorded
. Just click on "Video".
As long as it does not get in the way of the match I have no issue with streaming. But please wait till after to comment on the match.
Why you want no comments during the match? I ask because chatting/discussing with the viewers during the game makes it more appealing to them (at least a couple of them told me so and I would feel the same).
You think its unfair? If its a league or tournament game that might be an important factor, but most of these games are for fun anyway. And btw, if its unfair it is in favor of the opponent since he can see my spellbook and my prepared cards if he watches the stream
