Re: tikipedia (contact us)
If you're using the default application menu, "Contact us" (pointing to tiki-contact.php) will be added after the feature is turned on. If you have a custom menu, it can link to that page. (If the user is in a group that has the permission to use the internal messaging system, then there'll be a contact form on that page; otherwise there's email information.) Does this help?
