When they've broken the ice with you...

So, you've received an icebreaker. And it isn't a request for photos.

What does that mean? Well, here's some generalities that I've formulated.

If you've initiated communication
In this case, it doesn't mean much. It means you've intrigued her, but she's probably not willing to pay for a membership.

In this case, I'd either close her, or let her sit on the bottom of your match list until she decides to fork over some money.

Don't get your hopes up.

If you haven't initiated communication
Aww. How cute. She wants to show interest without looking like she's really showing interest.

But, yes, she is interested.

And, if you like fast-track communication, go ahead and initiate it. She'll probably accept it.

But, if you do this, make it short. Only show mild interest.

Let her work for more. She's already demonstrated that she will.
