Welcome to the MR2ROC Glossary thread.

This has been set up to bust some of the jargon encountered in the forums.

Over the coming months we'll build up the list of terms, abbreviations and acronyms. But only if you ask us to......  s:wink: :wink: s:wink:  ......So, if there's anything you'd like to see added, please post up in this thread. To keep this easy to navigate, your posts will be deleted as and when their content has been noted and/or terms have been shipped into the main listing.

Please keep this specific to the '2 and associated modifications - (we don't intend to feature acronyms of abbrevi-speak such as IMHO, LMAO etc.: you can find these almost anywhere on the interweb  s:lol: :lol: s:lol: )

Feedback always welcomed.

Enjoy!
