Hmm...'their' vs 'his/her'

[faemouse]

I recently got into a facebook fight with one of my aquaintences from highschool over the apropriateness of using 'their' as a gender neutral possesive adjective for the third person singular. According to the grammar text I use to teach ESL/TOEFL, 'their' has been an acceptable gender neutral alternative  to 'his or her' since at least 2003
