What are the features of wiki markup in VK?

Question

Social media

Good afternoon everyone!
I heard about the creation of a site from a group in VK. The fact that you can make a separate site that looks like a group, I understood that. Is it possible to make the group itself in VK like a website? That is, for example, to create an analogue of a personal account or individual correspondence between two people who are members of the community. At the same time, so that I, as the owner of the group, can see these correspondence.
