Some question need to ask...

Hi, my name is Sam and this is my first time using bitbucket, and I am still dummy yet.

(1) I am a piano teacher, and might have a few project with other music teachers too. So basically we will have a lots audio/video recording and a lots musical work sheet. And my question is do I allow upload mp3, ogg, midi, avi, mp4, and pdf files?? (my own record)

(2) How much maximum mb or files and the storage?

(3) How long inactive account will going suspend/banned?
