Common abbreviations and acronyms on this community

I recently received a suggestion that we have a section on this forum to explain some of the many abbreviations and acronyms that people commonly use. I have therefore set this up as a pinned post and will put in some of the ones that immediately spring to mind, but would also encourage you to:

a) Where possible, give the full version of a word you wish to abbreviate, with the abbreviated version in brackets after it, the first time you use it in a post.

b) Add to this post with other abbreviations/acronyms.

c) Please ONLY add to this post with other abbreviations/acronyms, so that people don't have lots of conversation to scroll through.

Here are some to start us off:
