I assume that you are talkink about Angela Edwards.
These are what I would call Sammy links - you are basically using a number of forums etc to get backlinks, in qantity from the same provider. Soon enough, most of these forums would be loaded with so many link cheats that the whole value of the forum would die out. You may get a short term boost, but I would advise against it.
Angela also sells her backlink packages to thousands of subscribers and I can assure you the forums and blogs that you post to get tons of comments daily and they will most likely be devalued over time.
I would maybe use some for a base for your backlinking if you must and concentrate more on quality backlinks such as EDU, GOV, actual page rank, these are far more valuable and Google respects these much more.
