Wasn't sure if this is the right place but when I was filling out the passport section of the mysos web version, it would complain if I had my first and middle name entered with a space in between. I went ahead and just entered my first name rather than smushing my first and middle name together.
The passport upload scan/picture was approved so I assume this isn't a problem.

Any experience or advice from others?

(Moderator if this needs to go elsewhere that is fine with me. It seems that we are going to start seeing more questions about mysos registration so maybe need a general thread for that?)
