  testing 2958: bplan verification mail
  **URL:** mail
  **user:** administration staff working via imperia
  **expected behaviour:** /
  **behaviour:** wording changed, see below
  **important screensize:**/
  **device & browser:** /
  **Comment/Question:**
  
  - cross out the word "Betreff" in e-mail-subject
  
  - correct "Projektü**n**ersicht" to "Projektübersicht"
  
  - can you write "Uhr" behind date and time?
  
  - I already know that it is complicated to separate date and time via comma, I guess this hasn't changed?
  
  - the word "identifier" shouldn't be there but I guess it is only there because you entered it into the field together with the identifier itself, right?
  
  Screenshot?
