Google friendly web forums

Hello. I thought I'd see if any of you know if there are any free web forum hosts that are google friendly? I'm trying to create a message forum like this for old cadillacs. I tried this one http://www.netfreehost.com/phpbb/ but google doesn't recognize it. I went to the google webmaster area where you can add the url and verify it. It says there are errors and google doesn't recognize it that site. It also says I need to verifiy by adding a META tag or an HTML file. I have not a clue on how to do that. I supposed I'm screwed since trying to use these free places. I figure if google cant find it, I'll never get anyone to see it. Thanks

To add a META tag, just add this to the HTML code above the </HEAD> tag:

<META NAME="keywords" CONTENT="insert words here for Google to look for">

ok, thankyou
