I've noticed that there are a certain number of abbreviations people use here for things which I don't know.

i've worked out that a therapist is a t, and what Csa means, but I've seen others such as mb which i don't understand, ---- are these in any way official, and if so is there a list?

then again though, sinse certain words and terminology, ---- -like the S word bother me, would it be better for me not to know some of these.

Any thoughts or information about this would be much appreciated.
