www.aziendainfiera.it

Hello everyone,
I’m trying to move on MODx rev. the www.aziendainfiera.it site.
It ’a site with 10,000 hits a day and I see how it behaves with MODx this amount of traffic.
Problems:
- Need for management of categories - sub - under subcategories (tags). How do you recommend to manage them?
- There is a plugin to handle multiple languages?
- There is a plugin easily build form to request info?

thank you very much
Fabry
