Perhaps I'll make a copy of the news module, change the references to the "news" directory to "news2" and then make my modifications on that module.
Yes, you can do that... start with the info.php file, that's the file that tells WB the name of the module, the folder to install it in, and other important information about the module.
But like was said, you can insert a news section on a page, put all your text in the "long" box, make it a hidden page then create a menu link to the static address of the page.
If you want multiple pages, make them all on the same hidden news page, and use menu links to them.
You can edit the settings so the bread crumbs and such are not shown.
One problem, is that every page like this would have the same page title.. unless 1) you change your template, or 2) I ended up creating a page and changed the page title to a single space (can't have it be blank) so it uses the "new title" like the page title. Though it does throw the formatting off a bit.
You may be better off if this does not work, is looking at modifying the GuestBook module rather than the news module... then your pages would have a WYSIWYG followed by a modified Guestbook section for making the comments.
There has to be a way to check if someone is logged in or not that should be fairly easy to add in there.
