About Page/ Impressum/ Contact/ Email?

I am using Gallery2.3 since one day. Have installed the greypop theme.

Now I am missing a page, where I can put some data about me, for people who want to contact me.

I have found in the forum an very old thread from 2006 with a zip containing an "about page" module. But it does not work in gallery2.3. So I wonder, if gallery2.3 has already a possibility to add an about page ore an impressum (it is regulated by law in germany that private websites need to have an impressum, as commercial sites need to have too). I did not find any possibility like that in my admin area

Can someone help me to creat some page, with a link at the bottom of the page or below the header?
