Username change and meter reading help

I would like to change my username, how do I do this?
Also I’ve entered my meter reading for my electric but it wouldn’t let me enter without filling all the box so I added an extra ‘0’ onto the end, should I have done this or is there a way it should of been entered?

We can change your username for you. What would you like it to be?

Your meter reading looks fine to me. A 0 after the decimal place is perfect :slight_smile:
