Hello
True say I not know what propose to you.
BookLibrray
ordasoft.com/book-library-joomla-ebook-extension is a component special for books. And all fields created special for books. If some field you leave empty - we will not show it on frontend.
If you need change how it look or work:
We may propose to you order this as "customization service".
Please write to OrdaSoft contact form (
ordasoft.com/contact-us-form) with full details description, how all must look and work, and we will give to you quota.
BUT, if you create one language site, or for translate of the site you use components for automatically site translate like SefTranslate Manager
ordasoft.com/sef-translate-joomla-translation-component.
I wish ask you, to take attention to OS CCK
ordasoft.com/cck-content-construction-kit-for-joomla.html
There you may create "Private forum" and you will self select which fields users can see. There you create all forms self with help Drag&Drop "Layout manager". There you may give possibility for users with more right to add (to see) more info....
Best Regards,
OrdaSoft team
