Virtual Queue

By using this plugin you'll be able to allow only a specific number of visitors to navigate through your website. The extra influx of visitors will be kept in a virtual queue until a new space will be available.

You could always use the following shortcode [virtual-queue-position], in order to display the current user position into the queue.
