Hi
I have a web site . but i can’t redesign it . my site <snip>
I’m a bit unsure why you’ve posted this, as you haven’t asked a question or requested any help.
If you’d like a site review, where other members can make suggestions about what you should change, then you can request that over at the Reviews forum. Be sure to read the guidelines there first: http://www.sitepoint.com/forums/showthread.php?744418-Read-before-requesting-a-review
if you wanna redesign it then you need to know all the core things about your site and all after that you can redesign with some suggestions. so be more specific to ask a question . The information is very low.
