phpBB newbie help

This is my first time using a forum so I’m still tinkering with it.

I have installed the eXtreme Styles mod to phpBB. Just wondering if there are any other useful mods that people use with phpBB.

Also I am unable to use the “Check Update” feature of the phpBB. It says it requires sockets to be enabled. Does DH enable it? Because when I try to check for update it says “Error: Unable to connect to server”. Any help on this issue?
