tutmae--Forgot to tell you that my VIP membership is only $10!! Although I think FF will tell you when you've O'ed without the VIP if you're logging enough symptoms, such as CM and CP, but both change frequently, so it's a more accurate read when it has the temps to go by. Oh wait, just re-read your question, I think as long as you're temping it'll show O, just won't show colored squares on your calendar--but then again I only got the first month for free, and started the VIP before I started temping, so I'm not really sure what happens when it's just regular membership. That was no help at all, I shouldn't have even bothered posting! I say go VIP!!
