Methinks the National Panhellenic Conference Manual of Information of information needs to be revised, at least as far as correct Greek pronunciation is concerned.

In Greek, Iota is pronounced along the lines of "yota." (If one says "EE-ota" like SAIrose suggests, but moves over the "EE" very fast, one ends up with something more like "yota," the "I" being a glide.)

In Greek, Mu and Nu are pronounced more like "Mee" and "Nee." (See "Upsilon" below.)

In Greek, Xi is pronounced "KSee," not "Zee." Similarly, Psi is pronounced "Psee."

In Greek, the "U" at the beginning of Upsilon is more along the lines of the "u" in the French "tu" or the German umlaut "ue" (or "u" with two dots over it, which I can't do in this post.) The tongue is held in position to say "ee," while the mouth is in position to say "oo."

AXPGoBot is right -- for GLOs, it's all a matter of preference and tradition.
