Suppose when you press join button (mostly at bottom scroll of page), they reload and start from top of page and again I have to go to bottom and select other topics. Instead make sure not to start from top when join button is pressed
Yes,this is the main problem. when we try to joi any group by pressing join button it carry us to the top of the page then we have to come back by scrolling and scrolling to the group which we have to join.
