We added some new stuff for tags.
From now you can allow other people to tag your photos. You can choose between your friends, active users(*) or any user logged in. Go to your prefs, choose "Permissions" ("Berechtingungen") and set your permissions. By default, your permissions are set to "Nobody".
(*) "Active users" simply means people who have more than 16 reports. We already have 73 active users now!!!
Other new thing is the new page what lists all tags in a gallery. For example, there are all tags for Sputnik: Sputnik's tags
Another tag-related feature is the Tag-Log. You can also access it from your tags page. The Tag-Log shows all tagging activity on hikr: who tagged what and when. This can be used with collaborative tagging, to see who tagged your photos.
We plan to extend collaborative tagging to reports and to geotags (add waypoint to photo / report) and probably some other parts of the site. Other related thing that is still missing is "all tags" page for reports and waypoints. And probably we will need an email-notifications of some sort to alert people that they were tagged.
Do you see any other feature that we can add for tags?
UPDATE: We added an icon to the People page that shows users who allows collaborative tagging. Colors mean: green - everybody can tag, orange - active users, red - friends.
