I was thinking that would be a conflict when I posted this yesterday. It can be a good thing and a bad thing. But I think more of a good thing to implement. Generally a low rank should not have many questions to ask or ideas to share since he is a new player. New players have enough to explore in the tutorial, plus we have plenty of helpful information here in the forums that they can look at, and most importantly they can always ask for help in room/help channels. Having these rank 0 accounts here isn't necessary.
If they really want to post here they should be of a required rank.. plus, it may motivate them to play and it will discourage these 'trolls' from trolling this place.
"Generally a low rank should not have many questions to ask or ideas to share since he is a new player"
This goes against logic. It's the exact opposite of what you wrote.
When you do something for the first time, do you have a lot of questions? Of course you do. You want to know what it actually is; how it works and so on.
"New players have enough to explore in the tutorial [..]"
The Tutorial is awful and currently under a revamp. Even after exploring that, one can still have many questions to ask.
"[..] and most importantly they can always ask for help in room/help channels."
Well, what if there was no one who answered their question? And this happens quite often - when I use my alts I see no one responds.
