K2 Comments not approved

Hi,
when user stored a comment on my website (www.tsv-bardowick-fussball.de), there is no approval message for the user, that his comment was stored. Can you give me an information how to solve this?
Kind regards
Jürgen

Did you check the K2 settings from backend ? You will find there all settings related with comments, for more informations about K2 you should look at K2 support forum because this is 3rd party extension.
