I am new to the site, I verified my email, but I still cannot send messages, does anyone know why?

You should be able to if you actually DID verify your
email so I attach the following in case you did not:

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 :-)
