Steps to reproduce:

1. Open the registration form,
2. Fill in the "Email" field with invalid data.
3. Fill in the remaining fields.

Expected result:
System message which indicates that the email is invalid. Have to be told the exact field which is not filled.

Actual result:
System message "Please fill all required fields" appears

That one is a good catch. A fix could be to use RegEx to look up for 'string@string.string' format i.e. to verify the email input is not missing neither '@' nor domain.
