Can I put online an accepted paper before the conference? My paper has been accepted for a conference, I have chosen the ACM "License to Publish" and the publishers are happy with the camera-ready copy. According to the ACM license I may 


  "Post the Accepted Version of the Work on (1) the Author’s home page,
  (2) the Owner’s institutional repository, or (3) any repository
  legally mandated by an agency funding the research on which the Work
  is based."


It doesn't say anything about the timing.  My question is: may I put it online on my own website before the conference?  And if yes, is that considered bad style?

As long as it does not say otherwise I would assume timing to not be an issue. That is, you are free to put the paper online before the conference, and indeed (at least in computer science) this is commonly done.
