Change certain words language translation

I misread your reply a bit... you can translate the "New" part of the phrase from the Email Digest Body Template. You'll need to drill down to the right location in the digest...

• Be sure you're editing Email Digest, Body template
• Double click on the first large section that includes the "new content count" token
• Double click the "Email Digest: Application List: New Content: Count" token
• Change the Template drop down to "Vary condition is false"
• You should see the place to change Nouveau to Nouvelle
• Click "OK" all the way back out and click "Save" on the plugin.

Thanks so much for your help, Steven & Mathew! Really appreciate it.
