Sample Users

Hope this is the correct place to post... it has been a while since I used Elgg but I am sure there used to be a plugin which would install a number of sample users. I am currently putting together a proof concept site and would like would like to populate the site with sample users/content so as to 'pad' it out for the talk I am giving. Does anyone know if this plugin still exists or is there an alternative (I am working on a 1.7 installation)
