We have a menu item in the top menu bar under "Basics" which says "Abbreviations". When you choose that menu item you first get to an intermediate page that explains a little bit about available abbreviations and glossaries:
forum.susana.org/component/content/article/27

Then one more click takes you to our brilliant new abbreviations list on Wikipedia:

en.wikipedia.org/wiki/List_of_abbreviations_used_in_sanitation

Every time I see an important abbreviation pop up, I add it to that list. And you can do the same (Mughal has set the example!). Just click on the edit button at the top of the list and add it. The list also functions like a glossary because I have hyperlinked all the terms to relevant Wikipedia articles.

Here you can see where to find the edit button on the Wikipedia page:





I hope you are finding this useful?

But in any case, I urge everyone to always spell out an abbreviation when you use it the first time in your post.
