Well, I'm actually trying to find the class of someone probably not in the same city, maybe even continent. essentially it's a addon that lets you flag certain classes you don't want to get whispers from when looking for more people for a party.
I was able to get the classes from SendWho/GetWhoInfo combo but I had to hook the chat frame, and parse some strings to hide the fact that I was doing so.. and there is always the potential of getting a bad class back (aka. Bob the Hunter messages me, and my addon SendWho's Bob, and returns the class of the first person in the who search, Bobby)
So, I was hoping maybe there was a more efficient way?
