i like the audio greeting, but would be nice to have an option to only greet the visitors only 1 time per session, or 1 time per every 7-8 page visits. when audio greeting is on, and users click on site links, the audio greeting keeps playing on every link click.
Thanks for your feedback and suggestion. We will add similar functionality on next release.
