Could anyone pls tell me, where I can find the Instant Message bar or function. I just cannot find it! Thanks.

hii welcome to mingle2 and to instant msg just go to the profile of the person u want to instant message there will be an option of instant msg click it and a window will open launching av messenger then wait for the person to accept ur request

From my account, go to setting, scroll down and turn on the instant messaging
hope that will help.

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.'
