I suggest changing to a darker font (text) color. It's a bit hard to read mid-light green over a white background. Changing the link color is also a good idea. I recommend learning CSS or at least using some CSS stylesheet generator, OR asking someone to make you a website template. I am willing to do that with some time.
I like the banner and menu images, though. Pretty clean. Good job on them!
With some work, this website could be successful. Just leave that .tk URL, please. Use
http://ne1.net. Their service is much better. Yes, adds a tab at the top, but you can exit it. And the address will be something like
www.mysite.r8.orgLast suggestion. DO NOT USE PHPBB! It's AWFUL! People don't realize how many bugs and security holes PHPBB has. It's too popular because it's old, not because it's the best. For free, easy to use and customize forums, and with better features, use
www.proboards.com and edit that template to make the forums look like the website. It's very easy, and the community is very helpful. Lots of tutorials and codes to add to the message board can be found at the support forums, AND you can edit almost every part of the forums' templates. Header, footer, inside each separate board, etc. If Proboards offered their software for individual download and install, I would use it without a doubt. I love it.
(For more specific links and tutorials, ask me. Oh! And Google Adsense doesn't (or rarely) accept websites hosted under ad-supported web hosting, or free web hosting.)
GOOD LUCK!
