[Chicago-talk] Regex question

[Mike Raffety]

Change the "Hello," to "Hello.*,", so it includes any characters between 
the salutation and the comma.

However, what I can't figure out is how to make it also substitute a string that already has a first name after hello.  For example, if finds Hello Kim, I want it to replace it with $ES.  Sorry for my ignorance.  Any help would be greatly appreciated.
