Is there an acronym definition list anywhere on MOSC?

Acronyms abound in MOSC (like MOSC), some of which I know, many of which I do not. Is there a resource that can give me a quick look at the spelled out name and perhaps a brief description? For instance, I read a post to do with 'ZA'. After reading I don't think that post applies to us and I think it is for Africa but am not totally certain because I don't know what ZA is. An acronym dictionary would be most helpful to those of us who are not reading MOSC daily. Thank you!
