Roblox allows players to create or join groups that highlight their own interests on the platform. The creator can change the name as well, but there's a fee involved.

On July 30, 2009, Roblox added a feature called groups. Any such team that a player creates or joins can have nearly an endless number of members.

How Can I Change My ROBLOX Display Name? You can change your Display Name for free, once every seven days. This is how other players see you in-game and isn’t unique to one player.
