A few weeks ago I set up a "social feed" I believe it was called, where I had the option to plug in a twitter hashtag and anything that appeared on twitter with that hashtag appeared in my Latest Activity stream.
Now for the life of me I can't find that setting anywhere to edit it with a new hashtag.
I'm going to write it down next time....:)
Go to My network>Settings>Ning Labs>Social Feed>Enable Feature>Settings>Twitter Search>Enter tabs and Save it.
Hope it helps you.
Doug don't feel bad. I did the same thing last month. Blamed it on turning 51. *lol*
