Ups fellows, I need your help.
Can someone please explain to me in street language including examples, The difference between RGD, RDG_A and RDG_B. Going out of town in the morning and won't have access to internet for a few days and need to sign up before i go and please don't send me the ipa web site since i don't get what it says and there is no one in the office to answer my questions.
Thanks for any help.
