You can use a translation file (using POEdit to change the data in languages directory) to change to any string you like. If you do an update in the en_US.po (or another depending on your site language) file, you should see strings like Name:, Email:, Phone: etc. in the strings list available for translation. You would then be able to input any alternate string of your choice there. You can get information from http://www.solostream.com/blog/tutorials/translate-wordpress-theme/ about translating your site into your language. Pls make sure you add the entry for your language into wp-config.php file like this –
define (‘WPLANG’, ‘fr_FR’);
Pls use the pot files in ‘extinct/languages’ folder as a template to create .po files. http://www.poedit.net/ -Poedit is the popular free editor for creating .po and the corresponding binary .mo files. You may need to do an update in POEdit to see all the strings. Do reach out to us in case you find something that is not translation ready.
