Make the sign form appear in the body page of the GB

Hi,

I have just installed the guestbook and it looks very nice. However, I would like to make the sign form which any user has to click on "sign the guestbook" to sign the guestbook appear in the body page after posted comments. This will make it easier for the users to post their comments without click on the link "sign the guestbook".

In addition, I would like to disable some options such as name, email, location, and image verification. I only need the message box and the submit, preview, button. Where could I disable these options?

Finally, I would like to hide the link "administration". Where could I do that?

Thank you very much for your kind help and wish to hear from you soon.
Albert
