Please help. n00b in trouble

[Synergy]

Im a complete noob to php i'll say that before i try to explain, ive never used or even thought of using php until 2 days ago.

Here is a link to my site:
http://synergy.servebeer.com/

Im using apache2triad to host my website also.

Now i will try to explain my problems

1. Im using php nuke and for some reason when people register the confirmation e-mail isnt sent. I think the problem is i need a web mail server or something like that but i am not sure.

2. Im using a php nuke theme by mtechnik and i need to install a mod of his called theme cp. I tryed installing it but when i go to html/install.php all i see is a blank page and the install didnt work.

Please help, thanks  :cookie:
