As for YouTube,
these are the official format recognized by our forums↓↓
http://www.youtube.com/watch?v=[video ID]&list=[list ID]
Video ID is the ID of video consists of letters and numbers.
YouTube is not the only one,
there are other services that can be embedded in our forums too like DailyMotion or Vevo.
We do not support pandora.tv like you posted,
so your deleted post with pandora.tv link cannot be embedded correctly,
but posting only the link as long as it is legal to share is alright,
it does not have to be an embedded video like La-san @laccal posted.
please remember that there might be videos that is restricted to certain country,
so even if it is viewable in your country,
it may not be viewable in country of other people and vice versa.
Official videos for Nogizaka46 are known to be restricted and only viewable in my country (Japan).
So please check audience restriction of a video before posting.
Good luck with posting,
and welcome to ScanLover ver. 2.0〜♪
