Build web page and subscription form / payment?

Can I build a web site over Splynx? I want to provide some info, videos, prices, etc… I need some navigation or at least a home page; can this be done?

Can I add a registration form / checkout so the users can register and pay the service from the web site? What would be the best practice to do this?

why not ? )

you can place your files to /var/www/splynx/web/

Great! I can now add pages, thank you.
Please, tell me, where can I start to add a subscription form for new users?
