Ah yes. I wouldn't bother opening this idea, but it would be cool if you could "fork" a thread to take ownership.
I would utilize Sanford Whiteman 's solution here. It's the most elegant and simple form of this IF/THEN velocity for salutation.
In our use case, we needed to be able to pivot the salutation based on the recipient's honorifics. So a Doctor would get "Hi Dr. Smith," whereas a staff member would get "Hi James,". To that end, you could really customize a salutation to whatever fits your business need, since you're evaluating a field's value to produce a desired output.
