Acronym Soup Dictionary

Generally speaking, it’s best to not use a bunch of acronyms when posting. This helps everyone understand what you mean. It also makes for a much easier-to-read community post. Obviously, in the tech world, some acronyms are just easier to use. If/when you do use acronyms, here is a collection of some common ones to help translate.

I will try to continue to grow this as we go. Let me know what I missed and what you would like to see added to the list.
