I'd like some suggestions

Hi!!!! I'm naly frrom Puerto Rico. We have a website that we've been building. I'm not an expert. I just did all these by reading the help and stuff.
The website is in Spanish , but the information is not important. Basically there's a lot of pictures, and we have a forum.It's a webpage for our honda/acura car club here in Puerto Rico.

So any suggestions and analysis are welcome!!!! I just want to learn. I was thinking of buying a book or something, or maybe take some classes, but maybe my work won't let me enough time to go out and take classes.

So you are the experts!!!!! You tell me.........

1) I would not use javascript-alert-boxes right when loading the page (in fact I would not use them at all)
2) The header picture/s are not same width than the table below those is.
3) the page itself seems a little messy. No offense meant on that, probably you could try to get the design a little cleaner, by using straight edges and splitting e.g. the screen visually up to 3-4 columns...

best regards

thanks for evaluating the page.
I really don't know anything, so I'm learning...

Tha java-script boxes? Are those the ones with the menu pages?

just realised this seems to be an error message, not programmed by you. Allthough I did not check your source code it´s more likely that you did not fit it in
nah not the menuboxes. an alert-box that pops up when viewinig your page
