My message is not sending and recieved to next person,pls help.

How do you know your messages are unsent or received?

If you have not verified your email account, which
everyone must do, try the following:

Send an email as directed below:

"For anybody that has checked their spam folder to no avail,
please send an email from your registered email address
to the following address:

m2.support@nextc.com

Give your message "verification" for its title."
~~~~~~~~~~~~~~~~~~~~~
So, you would go to whatever email you have listed here:
http://mingle2.com/inbox/mail_settings
and send an email to: m2.support@nextc.com
with "verification" as the subject.

They will take it from there :-)

hai any body can help some longer msg was not reached me ?

If you mean that your message was left unfinished because of
length, there is a very generous message length built into
the system.

But I also have hit it upon occasion.
I break the message into 2 parts at that point :-)
