hello, is there anyway to to give free access to anonymous users? so thay anybody that can sign without being a member?

if i can't, is there another good one for my users?

The XtremeUSERguestbook is a guestbook for members. Each member can have their own guestbook in which other members can sign. This module was written for the old XOOPS version.
If you want to have acces for ano-users, i'd suggest you install a common guestbookmodule (narga's guestbook module) and give the appr. read/write acces rights.

Grtz., Shine
