Membership, no email being sent to registered free users

I have free members enabled on my site (for the moment it's JUST free members), but they are not receiving the email that they should be getting right after they sign up. I have Buddypress managing the sign up form so I can gather additional info, and have enable incomplete sign-ups set to yes. There isn't an action for them to take when they have signed up, there is not button to click, etc.

See the screen shot of what they see right after they fill out the form, on subscription page 2. I added the text for them to click to login b/c there was no other action being defined.

Something just doesn't seem to be functioning correctly…
