• Deleted duplicate test case D_024
• Deleted the deprecated test D_016 nonLatinLetterEmailVerification as it is not applicable according to support for IDN (Internationalized Domain Name) and email addresses.
• Corrected the order of test numbering to match the document with test cases.
• Added new test D_002 verifyDiscussPageSpellingSignIn to check spelling on the sign-in window of the Discuss page.
• Added new test D_008 verifyTabKeySelectEmailCancelButton to check the functionality of the Cancel button when using the Tab key.
• Updated tests D_006, D_013, D_014, D_015, D_017, D_018, D_019, D_020, and D_021: Removed unnecessary timeouts. Added additional checks for the displayed/not displayed error message and its color.
• Reworked test D_026 for Chrome and Safari browsers: Chrome checks for whitespace in email input and prevents entry. Safari does not enforce this restriction.
