Welcome to the board!
Ok, she's shy and a bit timid, and is asking if you've checked the old profile mailbox, commented on how nice the swingers were, and said you can put the pics on the profile, and you haven't brought any of it up?
Yeah, I'd say she's interested. A lot interested. To steal a phrase from one of the other board members, I think she's hitting you with a clue-by-four.
Assuming you're still interested in swinging, ask her if she is interested the next time she brings it up. Let her know it is cool with you, since it sounds like that is what her concern is.
Good luck and keep us updated!
