can some one post some kind of tutorial or at least a bunch of links on how to work with both max and Maya seamlessly using the fbx files cause i have no idea at all i cant even find the extension in max

the main reason is because i am join a team of Maya users and am the only max user(LONG LIVE MAX) and i want to be able to help them using it.
if there is some kind of plug-ins, more helpful tweaks, previous known problems with this can you guys please state all the info you got AND DON'T WORRY ABOUT WRITING TOO MUCH PLEASE DO.
