Free website in various languages including English and Formmail php scripts

[Niffy]

Hello,
I wish to migrate my website from [host removed] to a free account here. I tried on FAQ and Wiki but was unable to find an answer to these questions:
Is it possible to add a domain free, like http://mydomain.com (without www), and would it also work with www.?
My website is in various languages *including* English and French. All the languages sections are more or less identical (at most some are updated more often but content and size remains very similar). Is this possible?
Does Tectite Formmail script (php with fsockopen) work here even to gmail accounts?
Thanks
