I’m trying to update `system_messages.welcome_tl1_user.text_body_template` and address the user’s name in the message, but getting the error: `The following interpolation key is invalid: name`: ![image](https://global.discourse-cdn.com/meta/original/4X/7/a/c/7acdd19ca4f1759e18a5e78fe5c3dd0652b8dde0.png) Is there a library or doc that I’m missing where we can see which variables can be used in which messages? ---

i think this may be your answer: > [@Available interpolation key(s)](https://meta.discourse.org/t/available-interpolation-key-s/126130/2): > > The only ones available are the ones in the original translation phrase. That’s it. ---

Thanks Lilly, that’s a bummer. It would be nice to address the user’s name in some of them. ---

This is not my area but taking a look at [`ALLOWED_CUSTOM_INTERPOLATION_KEYS`](https://github.com/discourse/discourse/blob/main/app/models/translation_override.rb) it appears you can use additional values for certain messages. In particular: ```plaintext %w[system_messages.welcome_user] => %w[username name name_or_username], ``` I think if we changed this to: ```plaintext %w[system_messages.welcome_] => %w[username name name_or_username], ``` It would let you use those for other welcome messages. I’ll ask around. ---

In theory we should be able to add all `system_messages.*` keys as long as they have `subject_template` and `text_body_template` subkeys. Because all of them should be handled by the `SystemMessage` class which adds `username, name, name_or_username` as additional interpolation keys. > ---

Could this behavior be extended to chat so notification emails can include the user’s name in the subject instead of their username? ---

you would have to edit the chat email text and change the key from username to their full name. but i have no idea if this is possible. the chat configuration is not my forte. i would go to `settings-customize-email` and search for a chat email template in the top drop down menu. all the editable email templates are in that drop down. ---
