At least not anywhere that we could see. They offer essentially a cPanel environment, so expect to do your typical ftp/file manager and phpMyAdmin work setting up typical test accounts. We believe that sub domains powered by WordPress would count toward the total number of sites. So a Small account or higher would be needed if you want to have a live site and a test site, leaving space for one more site beyond that (3 allowed in the Small Plan at Lightning Base.)
