Icy Phoenix

Hi, i have problems with the activation from users, several users don't active their accounts, this is cause the server mail (Hotmail), don't work with the links.

Then i want to change the text of the activation message, but i can't find it, i search in /languages/Spanish/mail/, and i can't find the text for change.

Please, i want to know only that, how to edit the text in the messages, that is sending after you register in the forum.

Thanks

inside email/html
check

admin_activate.tpl
user_activate.tpl

Thanks Zuker is solved, but the file was: user_welcome_inactive.tpl in /lenguage/my-language/email/html/

Cu and Thanks for your help.
