Could I get my name changed to "Alamo"? Don't know where else to request, thanks

You don’t request, you just do it yourself in your Settings https://www.speedrun.com/solidmax/settings

You can only do it once every 60 days though.

Could you read the answer right above you?

The name “Spirit” is already taken.
