Nings and Hackers

This week on Library 2.1 we looked ast Nings which are a mix of blogs, wikis and forums. I joined the Library 2.0 Ning (not run by the State Library) and that very same week the ning was dismantled (is that the word) due to hackers interfereing in the ning. This is a very real problem I'm wondering how many of these nings, blogs etc have to be abandoned because of hackers. Molly
