in case you're wondering...ning has made some changes. there is now a bar at the bottom of the screen whenever you are logged onto RUN...
here is what i copied from the network creators help page:
You can participate in the chatroom directly from any page of the social network, by accessing the Chat bar at the bottom of the page. From the Chat bar, you can see the number of members signed into Chat, pop the Chat window up, pop the Chat window out into a new window, and toggle your status as online or disconnected from Chat.
When you sign in to a social network with the Chat feature on it, you will automatically appear as "online" in the chatroom.
In the right column, a list of members currently in the chatroom appears.
Clicking on a member's profile photo pops up a dialogue that allows you to view their profile on the social network or initiate a private chat with them. When the member accepts, the two of you will be placed in your own separate chatroom. You can hop back into the main chatroom by clicking the "Main" tab.>>
what i didn't get from that was the how, so here it is: you can either click on the bar itself OR the little pop out arrow. clicking on the bar pulls it up onto your existing page. the arrow creates a pop out window.
