I have a software product that ready to launch and its totally free. I want to use Orange Box as my hosting service but I have got two questions. 

1. Can I know my overall download count even after one year ? not monthly. Does the count reset for every month (I'm sorry I'm not much experienced in this)

2. Do you (or Dropbox) terminate the link after certain period of time ? Can I keep the same link for years ?

Thank you for your assistance.
