Q: Can't it figure out a way to get me to the Guild Lobby?
A: It could, but it won't. Be in the Guild Lobby when you run the macro. It will run you to the right location as long as your mesh is OK.
Q: Will this macro manage my houses?
A: No.
Q: Will this macro be useful for Guild plots?
A: No.
Q: Will the macro buy my plots and or houses?
A: Nope, that's for you to do. I suggest you be ready to buy when you run it!
