Imagine that you are walking down the street, met an advertising agent that interests you. You ask to talk about the product, and it answers "not here, go here at this address - there you will learn everything!".
You will go? me not.
Learn to respect the newcomers and respect their desires, do not tell them where to go and what to do, help them. They want to see and receive information in their usual way, so the forum helps to keep the chronology of events that adds credibility to the project!

If you send everyone to the slack, you will lose potential investors.
1) Many trust this forum and look for information here.
2) Promotion should begin with an active discussion here on the forum. This topic should be on the front page.

Until you understand this, you will sit in your slack and talk to yourself, without new investors.

Start spreading the information, discussion ...
