How can i add or set more email tokens in my drupal 6 site I would like to add more email token variables in my Drupal 6 site.I have found some of the variables like !username, !temp, !site, !password, !uri, !uri_brief.Is there any way by which i could add more tokens and assign these token variables in my custom module.Could I accomplish this by using some contributed module or programatically.Hope someone could help me with this.
i guess you want more tokens in the users settings page admin/user/settings (D6), according the format of your token (!username)

This page is a bit special because it is a core feature.
cf User settings

Token module provides more tokens like [my-token] but this cannot be applied in the admin/user/settings

If you want more tokens on the users settings, i suggest to use a custom rule (fire on user's creation) with the rules module
