New guestbook entries aren't shown right away - I screen things for spam, questions (a guestbook is NO place for questions!), and things.
Have a private comment? Tell me.
"Boys from Cologna are good, and only have dumb things in their head"? Sounds ... weird for a dissertation.
This site is strictly wysiwyg - what you see is what you get - and I don't answer questions in my guestbook.
