Question

In contact with

Good evening. I want to add to the site the ability to receive a list of communities in which the visitor is a member and search for new communities by name.
Then you need to get the posts of the selected community and display them on the page (likes and reposts should also be visible). I once saw such a thing on one site, like on popsters. How to do it? Which method to use?
