[Camilo C Gonzalez]

only the first name should be on the first field, the C Gonzalez on the 2nd field.

Ok lets say there are 10000 (quite possible and probably even more) people with the name: "Camilo C Gonzalez" Is SRS really using names that are not unique as a way to identify? One person registers as "Camilo C Gonzalez" what are the other 9999 supposed to register as? "Camilo C Gonzalez1"? ... "Camilo C Gonzalez9999"?

Please register with your first and last names.
Ex: John Wayne

If the username is already taken, please add a middle name or initial letter.
Ex: John Smith Wayne or John S Wayne

What if John Wayne has no middle name or initial letter to use and a different John Wayne is already registered?
What if John Smith Wayne and John S Wayne already exist and another John Smith Wayne wants to register? What should they use? "John Smith Wayne SUPER-SECRET-UNIQUE-HASH-NO-ONE-ELSE-CAN-DREAM-OF"?

As far as I know middle names are put behind first name not into family name normally, when there are only 2 fields to fill out for names then either no middle name at all is used or middle name goes into given name field behind first given name.

The SRS registration and identification is confusing for sure and "seems broken".

I'm sure this may seem as a small issue if only a few users are on the site but anything bigger and the naming and identification is gonna be a nightmare.

You're right, it's a little confusing, I don't have a middle name so I've got to use the initial letter of my first name. Usernames are an aspect SRS needs to improve, however, I think this is the best way by the moment to identify racers because using nicknames is awful.
