I have only recently joined this site, and although it is interesting, very intersting in fact, I am stumped at some of the abbreviations that are used. I left the mob in 1980, and obviously things have changed. How's about one of the moderators compiling a glossary of abbreviations to put sad twats like me out of my miseY. The only ones that I remember is RN
R.N.D.Q's and R.O.M.F.T. 8)
If you can remember ROMFT, then you'll also remember RDP and DSMSMR.

Putting a glossary together would be a significant task as there's an awful lot of it about these days. Got any in particular which are doing your head in?

Weve been here before, why not stop using acronyms? at least at the first stage, not like someone on another thread that said "If you dont understand the acronym you shouldnt be reading the forum"
This has been discussed before in the context of setting up a RumRationPedia similar to AarsePedia - but with the obvious corrections!

We need to set up some suitable page on the site where we can enter acronyms on one side and what they mean on the other - acessible to all RR's to alter. Is this something the Mods could consider perhaps?

Here are some of the abbreviations we use at work, some obvoius, some not so.
See how many you get:
