I've just learned a bunch of stuff today after doing a little internet searching...this link is equifax talking specifically about the effect of creditors who don't post cl or balance info... It looks like if no cl it hurts and no balance, it might help it I read this right. http://www.jawewers.com/Position Paper on High Credit.pdf
now if you go back to the original website it is a professional writer posting samples of her work. Some samples of jennifer's other Equifax writings... http://www.jawewers.com/Equifax and Compliance Data Center.pdf http://www.jawewers.com/Risk & Usage.pdf and my personal favorite http://www.jawewers.com/BNI.pdf which of course isn't signed by the person who wrote it (like good old glenn king)
