Translation of Mahnung

I need to write you one more sentence. This is what my teacher told me and the German language is so difficult. So please, as a last favor, would you please write the sentence for me in German?
I would not put the box on the front page, you have it in the menu. But, if you want to have links from within your main page, put regular links within the introduction text, directly to the Spanish page.
We added all tenses to the online conjugator. Please have a look. Please tell me if you like it, whether it is useful to you and whether you would integrate it into your homepage for language studies.
