In answer to your questions:
1. This is not a default feature of the theme, however it is available through use of the
FXtender pro plugin.
2. Outside of the main subscription option shown on the
demo site sidebar, job seekers have alert settings within their own dashboard. It would require customization on your part if you were looking to make changes to this, however it is possible as the theme is not encrypted, so you are free to make modifications if you wish. Thanks.
