I have tried to thank people who upvote and follow them but nothing comes back in response.
Maybe the community is new and needs a notification area so we can know who is been active on our profiles and engaging and who is not.
Now that's what it needs.
Hello, we already have a notification area in "replies" tab.
From what I can see many users answer to comments and replies, more than on other social networks.
Of course, we can not always expect prompt and sure feedback, but I think this is quite normal.
Cheers!
