So I've messaged sentnudges and have yet to get one reply? someones gotta be on??

There is no one here you have reached a worm whole in space.

Members don't stay online 24/7 waiting for complete strangers to nudge and message them.

Members have lives outside of Mingle2 (except for me).

Also, the fact that you send a message or nudge doesn't imply that the other person must respond.
I routinely ignore nudges from complete strangers.

There is no one here except the pixels trying to escape your screen...

Well some do not respond to nudges... The women get wayyy too many in a day to respond to them all. ( probably?)

And I usually don't even mess with a woman's profile it has been more than a month since last log in.. They probably find what peeks their interest with in a week or two.. Not to mention people will have their own ranges they are willing to be remotely interested in contacting.

But best of luck to you.
