Abreviations
I can also relate to the need and use of the abreviations here and this board, and it is not particular to MERB in any case, try any board on the hobby and you will find them from TER and Doggiedog in the USA to La Guide Rose in Europe.
Look at any sigth from SPs and agencies and there they are. Otherwise completely uncomprehensible Hong Kong agency sites are understandable when you see the picture and the service line with the abreviations applicable.
Abbreviations allow us all to understand the same thing the same way if possible and make the description of a sesion by a Japanese bussines guy in Thailand understandable to an American in Montreal.
Yet, the abuse of some of them, by people outsise the boards confuse me. I have asked this question in several ocassions to no satisfactory answer, if you use an abreviation with no meaning, then the whole purpose of the abreviation is defeated.
I'm still looking for the meaning of YMMV++
