Is there a glossary of the acronyms commonly used here. The only one I understand so far is FIRE :)
Do you have any specific ones in mind? We're happy to help out.
I got stuck on these at first:
DH-dear husband
DW-dear wife
DD-dear daughter
DS-dear son
AA-asset allocation
IIRC- if I recall correctly
OP- original poster = the person who started the thread
Random letters- most likely an abbreviation for a recent poster's user name.
