Redmine

Hello There,

ive got a question.

One of my Redmine-User want to receive only one E-Mail at the assign of the Ticket to him.
When someone assign him a Ticket, he want to get an E-Mail.
When someone make changes at the Ticket, he dont want to get an E-Mail. This means all changes (assignment, due-date etc...)

I tried the notify-option "Only tasks which i am responsible for" but this option isnt the right one for him.

Ive searched for an E-Mail notify menue or something, but i dont find a menue or a mask, where i can change the E-Mail notify options.

Could you please help me to help this User?

FYI:
We got Redmine 1.1.2.stable (MySQL)
On a Windows Server 2008

Thanks in advance!
