Add nicknames, they would be changable in the Account Settings. It would be very useful, and like usernames, only one nickname can be used by one person, so two people would not have the same nickname. The @ thing would work with nicknames, and they would appear in place of the regular username, with the regular username below it. That way, the usernames would not be changed, and all posts with a changed nickname would change to the correct one. So if someone's nickname was Potato, and someone posted @Potato in a comment, then the nickname was changed to Tomato, the comment would change to @Tomato

Interesting idea. I semi-support this. It would be cool to see this, but I could see that the nicknames might block users from making a username that they like because the name is already someone else's nickname.

They could remove/replace certain letters, like an a would become a q. Or they could add slightly more letters, like Potatoo.

This has been rejected by the Scratch Team.

7.1 Changing usernames
If a user could change his or her username (or even set a certain “nickname”), this could be very confusing for the Scratch community, especially for those following that user. In addition, this would make moderation of the website more difficult because it would be harder for the Scratch Team to keep an eye on what a user may be doing. It could also be hard on the servers. The Scratch Team has allowed username changes only on very rare occasions, such as if the username contained inappropriate or revealing content. Generally the Scratch Team does not change usernames on request (such as “I do not like my current username anymore”).

That is not what I am suggesting, it's nicknames that replace your username but you can still do @Mr_PenguinAlex and the normal username would still be under it.

Did you see this link? It explains why nicknames are rejected.
