Hey Judy,
There is a long list of comments on
Interview with Greg McKnight, Legisi at No Bullshit HYIP Blog, A Part of No Bullshit Network. I believe it has the most comments of any article on NoBS. That should be a good start for you, especially since lots of the comments are recent.
Caution should be used with a HYIP this old when no one has verified their method for generating revenue. If they have a real business behind the "loans", then they are a good bet. If the are just really good at handling members funds coming and going out, then their time might be about up. I am really not sure.
JMO,
Sharon
