These lists are way to early to publish. For starters, not all students are doing the AOA match. A good number of my classmates are doing the allopathic match, there for those results will not be available until after March 15 or whatever day the match is.
To answer the above question, you can rank as many places as your little heart desires. But you can only match to 1 place. And if you plan on doing both the AOA and the AMA match realize this, that once you match into the AOA program, you are automatically pulled from the AMA match.
When you match to a program, this is a binding contract. You have agreed to attend their program for at least 1 year. Therefor you need to make sure that whatever you put on your list, you intend to attend if you match there. That being said, remember that everything costs money. So for the first bunch of programs you list, it is free after that it will cost you per program.
Finally, as stated before, these are very preliminary results and do not reflect those that did not participate in the AOA match so they can participate in the AMA match. Wait one more month for the final results.
