Since there is no way currently to quickly and easily subscribe to a community from the search menu, sharunkumar (not me) added a way to do that in this pull request.

There are 2 poosible designs that are consistent with UI of voyager so I will comment the images of the design below. Upvote the design that you prefer. Please refrain from downvoting.

Also it would be appreciated if the mod (@[email protected] @[email protected]) can pin this post (for a day or two) to ensure that it reaches most members of the community
