This is a compilation of commonly used acronyms here at Challengertalk contributed by the members. If you are new to the forum, or just wonder what the heck MDS is, or SPAG, you will hopefully find it here. This isn't meant to be a list of common acronyms on the internet, but rather acronyms that are more specific to Challengertalk. Feel free to suggest any that we have missed so far, and I will add them if they fit the criteria. Thanks to everyone who has contributed to the list
