To Facebook or Not to Facebook

Should a school district's leadership be nervous about creating a Facebook page? We were looking at creating a Facebook page for our high school, and it seems that we have hit a road block...we would like to be able to post without receiving comments from fans of our page. I have not been able to find a setting that would allow me to completely turn off the comment feature...I am not sure that I want to. I think that providing information, reminders of events, and highlights of the great things that our teachers and students are doing far outweighs any negative press you may receive through the comment section of a Facebook page. Moreover, you could simply delete the comment or ban the person from being a "fan" of your page if you don't mind violating the 1st Amendment...If anyone knows how to turn the comments off, please let me know.
