Αυθεντικό κείμενο - Αγγλικά - Holiday group social network invite

I have created a social network group for people who stayed at our hotel resort in Summer 2008. Many guests are Russian and I want to send them invites in their own language (This particular invite is for guests I have found via a video search feature on the social network). The words in square brackets do not need translating. Many thanks for your help.
