That's awesome- congrats! Our SW visits were pretty laid-back too. Does your homestudy agency require any references? We wanted to wait a little longer to tell friends and family too but we needed letters of reference and didn't want it getting "leaked" to our families if we told those few friends first. Good luck with everything!
Yes our Agency requires 5 letters- 4 friends/co-workers and then 1 family member. I was sooo nervous to ask for them because we aren't sharing until we're home study approved and on the waiting list but I think we made it pretty clear to our friends and my cousin to keep our secret quite for awhile.
