The following people have graciously made translations of the FormBuilder system for us. In order to use these translations, your WordPress blog must be configured to be using the translation in question. You would then simply put the translation file into your /lang/ folder under the FormBuilder plugin root. For example, if you were using the Estonian language translation of WordPress, in order to have the WP interface also appear in Estonian, you would put the formbuilder-et.mo file in your /wp-content/plugins/formbuilder/lang/ folder. It should begin to work automatically.  You may need to unzip the file before uploading to your server.
