Rating: You can rate other users' review from level 4 on. There is a logical structure to the system of user levels:
- in the "rookie" levels 1, 2 and 3 you can only
add content - and almost everything you submit is checked and/or rated by other users.
- in the advanced levels 4, 5 and 6 you can
check/rate/verify others users' contributions (starting with the right to rate reviews in level 4 and incrementally expanding to the right to confirm hotel information entered by other users in level 6) - but contributions you have made yourself still have to be verified.
- In the senior levels (7 and higher) you can add content without verification by other users.
Yes, the community is very helpful. And yes, there is a lot of German content at the moment, but the UK side is catching up. Normally German content should be invisible to you unless you checked "German" as one of your languages in your settings. Then both German and English content will be displayed.
