Hi Jack - welcome to the MA Studies Network. I had forgotten that you're the voice of Mass Moments! (they're embedded on the homepage of the network, as you might have seen.) Now I'll hear your voice each time I read one ;)
Anyway, feel free to explore, start a discussion, create an interest group, post an event listing, add other members as "colleagues" (our version of FB 'friends' ;)) or whatever you like to settle into this network. Just let me know if you have any questions.
