What do the different abbreviations mean in front of peoples screen names  ie:  NM etc.  I assume it has something to do with "master"?

NM - National Master

FM - FIDE Master

WFM - Womans FIDE Master

IM - International Master

WIM - Womans International Master

GM - Grand Master

WGM - Womans Grand Master 

NM is National Master.

GM is Grand Master. (2500+)

IM is international Master. (2400+)

FM is Fide Master. (2300+)

The female equivilant has a W in front. e.g. WGM 

Super GM is 2600+ i think.
