Sythe, or Matthew would need to be persuaded into adding such minirank to the minirank database.
For such thing to happen, you or someone else would need to come up with an idea of why to add such minirank to the database and then have Sythe, or Matther to approve the idea.
The question was how do YOU get Tesla minirank, so here are some ways of achieving that:
The proposal of adding Tesla minirank to the database should describe how the minirank is distributed.
You can request one minirank for youself for either comming up with the idea, designing the minirank, or meething the criteria of the distribution (whatever it is).
Alternatively you can request existing minirank to be added to your profile in exchange for 6 SOTM points.
Not likely, but you asked.
Best regards,
