General discussion

I was wondering if it is possible to create a discussion or forum area within the content.  Similar to this discussion forum.

I am not sure if there is a way to do this and I just don't know how.  Is there a way to create a discussion area within the content similar to the forum we are using here? 

Hi,

I am trying an interactive video which works great on my laptop with chrome.  However, when I try it on my mobile device (iphone 5) I press play on the video but it is just black with the sound playing

i have tried this with both safari and chrome on a mobile device.

images attached

Any help would be much appreciated

thanks
