As originally stated in the initial Guestbook post:
Please sign it with your messages and greetings to the original Yellow Deli folks, as well as any comments or suggestion about the site.br />The purpose of this guestbook is create a place to exchange greetings and reconnect old friends who knew us from thirty years ago. We reserve the right to edit or remove content deemed inappropriate or off-topic. We also have word filters in place to immediately remove profanity or coarse language (this is a family-oriented site, after all).
In the end, Philipians 4:8 is the guideline for appropriate content: "Finally, brothers, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable, if anything is excellent or praiseworthy, think about such things."
