How to change the words in contact form?

Hi, me again. Just wonder how to change the language for (NAME), (EMAIL), (Your Message ) as well as the button (Send Message).

http://demo.gavick.com/joomla25/creativity/#gkBottom1-3

Try to do the language override but cannot find them. As try to modify the source file but got no luck.

Appreciate your prompt help!

Thanks!

Please open GK Contact plugin via plugin manager and there you can specify part of module text.

Thanks, but I can't see any option to change the text for the input form.
Only these options:

Name fieldNoYes
E-mail fieldNoYes
Title fieldNoYes
Use reCAPTCHANoYes

Are you sure you didnt mistake what I meant? I meant the label for the input fields indeed. Sorry for making confusions.

Or check the file:
/administrator/language/en-GB/en-GB.plg_system_gkcontact.ini
PLG_GKCONTACT_NAME_PLACEHOLDER="Name"
and next lines.

Hey thanks, but I cannot find the file indeed in that directory. @@

Have You been installing from quickstart file?
If so - the file must be there (there is also file with same name but with .sys.ini at the end).
