Yet it's not entirely wrong in either case - unless I'm gravely mistaken.
Since English is my fourth language - I tend to use older grammar, as I'm not being updated on a regular basis (school is now long past due).
Although I stand corrected and should perhaps use less punctuation where possible. It easily becomes a bad habbit..
