This thread has been really helpful. As much as I love the idea of being "virtual" the sphere of prospects in my area have not quite yet grasped the idea of "virtual". Especially in the non profit sphere. However, I have decided to still use virtual in my name because that is the foundation of my business plan to be an assistant but not really be a physical employee. It really is a personal preference. I guess whatever you decide the marketing strategy is key.
I really appreciate being able to see things from so many different angles. :p
