You can't.
What i would try is setting your signature as a template and then insert it in every message!! I just got my Nokia and ya that works!
If they say 'Inbox me!' or something like that they mean they want you to add them as a friend on facebook.
It automatically adds new Emails to inbox. You do not have to refresh every time to do that. Whenever a mail comes, it is reflected in your inbox.
At the title sceen, you have to select "Wonder Mail". Then, you have to search online for a password. Different passwords unlock different missions to get different stuff. Once you type in a correct password, you may be asked to delete mail because you can't add the mail because your inbox is full.
It depends on the type of nokia phone that you have. Most nokia phones has a microSD card slot so you can add more memory to your phone.
Send Via MMS
I found out that you can't. Not to where it's automatic anyways. I have a Nokia 5800 XpressMusic phone and I've searched everywhere on my phone and online. Best bet is to create a text template and use it each time, or copy/past each time ):
add a password
Very odd, but the most popular password is password! Though people do add numbers and * ect.
You could just add a message on their message board.
For a system administrator to add a Samba password for a new user, they have to first add the new user name, then the new user password via commands. To add the username, add the command line, "adducer (name)" or "# user add (name)." Once they have their account, the administrator can add the command line, "# smbpasswd -a (name)".
