[Evolution] Editing templates?

[Mikhail Ramendik <mr ramendik ru>]

Hello!

I am using Ximian Evolution 1.2.3.

I would like to change the templates for new messages and replies. 

For example, my locale and language is set to Russian, and so the date
in the reply is given in Russian. This is bad for international list; I
want to either change it to English or just remove the date altogether.

Also, I'd like to add a default 'Hello %name' before the message.

Can this be done, and of so, how?

Thanks in advance.
