Does anyone here have experience with an online MBA program?

What accreditations are most important when evaluating options?

Does the US News and World Reports list have credibility for evaluating/ranking MBA programs?

In terms of the actual program, I realize being online I will have to be disciplined! This aspect kind of scares me a little, so if anyone can talk to that aspect it would be great.

My company has some preferred programs in which we get discounts, but I don't want to limit my possibilities to only those schools on the list.

Thanks in advance for any insight you can offer.
