Quick and Dirty..i am going to show you a quick hack which allows you to use a video to encourage participation in a group on your ning network.
Here's the scenario:
~Let's say you have a new group on your network called Total Station Talk (like I recently made)
~Now let's say you have gone to Youtube and found a video about total stations that you want to embed into your network like this one
~Now let's say you are interested in using this video to introduce or encourage the joining of the group. What you will want to do is inspect and grab the sprite code which usually shows up inside the group for joining the group, wrap it in a div and place it inside the description of the video. That code looks like this:
<a class="xg_sprite xg_sprite-add" dojotype="PostLink" _checkpaywall="true" _href="#"
_url="http://yournetwork.com/group/your-group/join">Join Your Group</a>
NOTE: make sure the code doesn't drop down and create any additional line breaks when you paste it into the description. Otherwise it will break the sprite
What you end up with is something like this:
