I checked out the validation link that Fibula suggested, and got a reply to say my site had only 10 problems! I was very surprised, an pleased but I have no idea what the 10 problems actually mean or how to fix them. I am not a tech head, as you can guess.

my site is www.chinatogalway.com
maybe any blind/ visualy impared members could check it out. I am not promising that the site will be 'the perfect site' but I sure would be interested in giving it a shot !
