As there were too many Spam-Entries, I was forced to code the guestbook in that way that I have to approve entries before publishing them. I hope, this will not prevent you from signing in. I'm happy about every Non-Spam-Entry und want to thank you very much for your opinions about my homepage or any other acknowledgements.
