Nintendo has released an update to Miiverse which added two new features, one of which restricts posting in quick succession.
Players can now no longer post several comments in quick succession on somebody else’s post. What this means, is that once a comment is posted, you will have to wait three minutes to post again on the same post. This won’t apply to your own posts, as you will still be able to comment as frequently as you like.
A Posts from Verified Users icon will now be featured at the top of the Communities screen, which allows users to display only posts by verified users.
The community search function, which lets you search for communities by software title, has also been added.
All versions of Miiverse are affected by the new update in order to “bring it in line with the Wii U and 3DS versions.”
