A welcome from me, also!
What is your end goal? Are you wanting to be a professor? Saying, you might want to check around and make sure the schools you would be interested in would "accept" the online degree.
Also, might I recommend looking at the program and seeing how much of it would work into a doctoral program. You would go into the master's program with the goal of having as much as possible going towards your PhD. You don't want to give your time, effort, and money to classes and find out you lose a year or so.
