vBulletin Manual - Adding or Editing a Phrase

Adding a phrase is straight forward.

Phrase Type – the type (or group) that this phrase will be put it. It will only be loaded by pages that load that group.
Varname – the variable name of the phrase that will be used to identify the phrase in code. You may only use a-z, A-Z, 0-9, and _ in the name.
Text – the default text of the phrase. You may use {1}, {2}, etc to represent variable parts of a phrase.

Note:

When editing a phrase, the options listed above may not be available. You will have to delete and recreate the phrase and translations to change these values.

Below this is a text area for each language on the board. Here you may create any translations necessary; if you leave the box blank, the value from the Text box will be used. You may specify a translation at any point.

Note:

To delete a translation, simply remove the text in the translation box.
