I had forgotten that feeling. I have long since lost the ability to speak WITHOUT acroymns. But FSO Spouse over at EF'M: The Life of a Foreign Service Spouse is currently going through that trial by fire, though I suspect that it may be more difficult for him as a spouse than it is for employees. We are sort of on an acronym immersion tour at FSI...
Anyway, he has drafted a very handy chart for you to begin learning FS acronyms. They are funny before you join the service, and hysterical after!

Speaking of EFMs, DiploLife noted today some resources for Trailing Spouses, including a Trailing Spouse Network group on LinkedIn with 198 members, that might be a good resource for networking overseas. DiploLife also mentions Ex-Pat Blog, which lists country related tips, blogs, discussions and individuals.
