Ning seems pretty straight forward. I opted to not open a NING account. Later maybe, I just have too many id's and sites to keep up with!
All searches I requested returned an answer unless I used a personal name. One of the searches was for mystery books and "The Sherlock Holmes Social Network" group was found. This was really a fun site for Sherlockians. I did get a kick out of a search for North Texas. One of the results was the Texas International Hair Show billed as
"The Largest Hair Show In Texas." This just goes to prove that Texas does have big hair!
