First BFR...what should I expect?

Go get your FAA "Wings" profiecency certificate - it counts as a BFR and
may
get you some reduction in your insurance costs.

Does anyone know how to actually sign up for this? G

You attend a seminar - if you're signed up for the FAA safety briefings
they'll send you notices via email. If you're a member of AOPA, when they
sponsor a seminar, they'll also mail you a postcard.

You can also get seminar credit from one or more Air Safety Foundation
online courses. Upon completion you print off a certificate.

Once you have the seminar done, you need 3 hours of flight - 1 for hood, 1
for takeoff/landings, and 1 for general air work. You can do them all the
same day if you want.

Upon completion, you have your CFI sign your log book (there's a certain set
of words, citing of FARs, etc.), and he/she also signs the seminar form. You
then mail the form off to your local FSDO, and in a few days you get a nice
certificate and set of wings.

A Wings phase completion counts just like a BFR (good for 2 years), but I do
mine once a year just to give me a good reason to get continuing training.
You have to wait 12 calendar months to apply for your next Wings phase.
