Thread:Support/Internationalization of "suppressredirect" user group

We need three Mediawikimessages for internationalization of "suppressredirect" user group; this group is available in our ckb.Wikipedia and also in Russian Wikipedia. How can we create these messages in Translatewiki? Thank you.
 * 1) Mediawiki:Group-suppressredirect
 * 2) Mediawiki:Group-suppressredirect-member
 * 3) Mediawiki:Grouppage-suppressredirect
