Is there a secure chat function on here that I and the individual I am corresponding to are curious to utilize for safety/security of self?
Something like a chat screen that stays within the site, and does not ask you to offer your personal (skype, msn, yahoo, etc)IM/ chat ?

Yes, as it happens :-)

HOW DO I IM?
First, you must have YOUR 'Instant Messaging'
turned ON:
http://mingle2.com/user/enable_im
(Or >>My Account>>Settings>>Turn ON IM)

Then you would go to the profile of the person
with whom you wish to chat.

Under their picture there is an orange button
'Instant Message' which you would click on and
the request to Instant Message is sent.

If there is no orange button labeled 'Instant
Message' it could mean one of two things.

The person does NOT have 'Instant Messaging'
turned ON.
(In which case you could email them and request
they turn it ON.)

Or, the person is in 'Stealth Mode.'

NOTE: The mobile site has NO Instant Messenger.

There is also a new chat feature, found floating
on the bottom right side of your screen.

Thank you for the reply. The individual states that the "IM" doesn't work on an iPad....is this correct, or is it a "ploy" to get me to contact them with private menas?
