回复：playlist 是什么，能示范一下吗?

建立playlist就可以在在一个窗框或者多个窗框中post几个视频.如下面这个帖:

建立Youtube Playlist 的方法:
01.create your own account on Youtube
02.create a playlist:
在你选的视频下, From the dropdown menu, choose "[New Playlist]", and click "OK." You'll be taken to a page where you can set the properties for your Playlist. Click the "Save Playlist Info" button. You'll be returned to the video watch page and the video will automatically be added to your new Playlist.

在你的 Playlist的embed 一栏里的CODE拿过来就可以贴了.

如果觉得上面这些步骤麻烦,也可以把一种类型的视频放在一个帖里集中一下也不错:)))

聂耳周末愉快~~!
