Hello Miguel,
1. Cultures for your site can be managed in
Site Manager -> Sites -> <edit your site> -> Cultures. If you want to add Spanish culture, just click Add cultures button and select the preferred culture version for this language. Please see
Developer's Guide - Configuring multilingual content for more details.
2. Are you referring to the
Content management section on the left side in
CMS Desk -> Content? If that is the case, then ordering them according to the last edited time is unfortunately not supported. But you can still drag and drop them and edit their order thihs way.
3. a) I am not entirely sure what you mean - is it E-commerce customers and the tax they pay? Could you please specify it further?
b) Page views are stored when
Web Analytics module is enabled.
c) Getting information about the most involved members in the forums can be done through
Tracking of activities.
4. All media files and content are usually saved in
Media Library.
5. This information is usually sent using
Newsletters.
6. You need to have
Smart search indexing enabled in
Site Manager -> Settings -> System -> Search settings. Also, it is necessary to rebuild the index after you create to get all documents indexed.
But as FroggEye pointed out, almost all information can be found in
documentation.
Best regards,
Filip Ligac
