I asked where these managers are, they are not visible and not audible.
They are where their job is? Go to discord you will find them there. Or go to telegram and say hello.
Don't know what you are talking about? Just because they have no bitcointalk account or they use a different nick here? It's not all about this forum. In fact it is a quiete small place these days with not that much action. Nowerdays all happens in discord. This is the most active place if you want to stay tuned to all what happens to the coin.
https://discord.gg/7a7XRZrand what's bad to publish information in the open access to this forum? why do we need closed groups? Is there anything to hide from the public?
Nope. I don't understand either why the team is not active here. I told them a bunch of times that this should be done but they don't seem to care. Nothing to hide since the discord is also public and you can see all of the history of the channel once you join in. Discord is as open access as this forum here. Just a different and to be honest way more convinient way to publish news.
You should join if you are not already

p.s.: as I said I have the feeling that the high times of this forum are over. Every thread I am interested in seems to be dead. Everything is in discord now. That's how things have changed and one need to adapt to this.
