We changed our notification system. Before you only could choose if you want to receive every day the updates of your friends and communities.
Now you can choose much more: you can choose the frequency of those notifications between "hourly", "daily" and "weekly" and you can specify exactly which notification you want.
It is no more necessary to add someone to your friends or to be member of a community in order to receive the notification about an update of the user or of the community. Moreover, you can also receive updates of a region or of a geotag.
You can administrate all your notifications in the menu Preferences -->News and Updates: www.hikr.org/edit_user_newsletter.php.
You can also add/remove something from your notification using the button "E-mail Abo". You find this button on the user's homepage, on the region's homepage, on the community's homepage and on the geotag's homepage.
TIP: You can receive all new publications by email if you subscribe to the region "World"
