Hey there, i have nuke 6.0 running but i have some problems. Here they are:

Everytime someone tries to register they don't get the e-mail with their password and they get this error message: Fatal error: Call to undefined function: mail() in /users/curvedspaces.com/jediclan/modules/Your_Account/index.php on line 119

Their account is created but they can't log in cause they didn't get the e-mail with the password.
It also happens with feedback or recommend us, both don't work.

Another problem i've found is this:
I can't validate my downloads, it gives me another error message. Like this: Fatal error: Call to undefined function: fsockopen() in /users/curvedspaces.com/jediclan/admin/modules/download.php on line 939

Hope someone can help me with this. Thank you very much.
