Here's one I did a while ago, concept is pretty straightforward.
When someone enters a new message, its saved in "new_entries.txt" 
wich only the admin can view after loggin in via a blind button in the top left corner (admin/password)
There the admin can preview the new entries and delete whatevers unwanted. (watch the seperators; "^^^")

When approved, click the "save" button to copie the new entries into "guestbook.txt" 
and clear "new_entries.txt".

If you want I can post the files later this week, there on my other system
If I forget about it, just repost or mail, cause these are busy times :D

Hier mal ne version die die eintrag zuerst in nem txt speichert das nur der admin sehen kann,
wenn gechecked kann der admin es zu "offentliche" beitrge hinzufgen oda lschen
