Join Facebook to School once accepted?

My dd has now been accepted to a number of schools and has not yet decided where she will go. There are two more highly selective schools that she will not receive a decision from until March. Knowing that, is it ok to still join the Facebook page for accepted students to a couple of the other schools where she is accepted and are serious considerations for enrollment? On the one hand, she is interested to see the student comments on these pages, on the other, she doesn't want the two colleges she is waiting to hear from to see that she is accepted to other schools and participating in the Facebook pages for fear of lessening her chances of acceptances. Any thoughts are appreciated! Thanks!
