Under each node there is a 'Add Comment' text. For a particular content type I want to change the text to 'review by adding comment". How do I do this?
Try with the String Overrides module. Here is a quote about it (from the module's project page):
Provides a quick and easy way to replace any text on the site.
- Easily replace anything that's passed through t()
- Locale support, allowing you to override strings in any language
- Ability to import/export *.po files, for easy migration from the Locale module
- Note that this is not a replacement to Locale as having thousands of overrides can cause more pain then benefit. Use this only if you need a few easy text changes.
