I joined last year during my first year in the MAT program. I've participated with some things on my campus and I've also signed up for a webinar about finding money for grad school http://www.kdp.org/teachingresources/podcastsechapter.php#entering
I get the Record about 4 times a year and I've used the free articles online for some of my papers. I think it's a great value for only $38 and I am looking forward to staying involved after I graduate (hopefully!) this spring.
