You mean sight as in web site and not eye sight?
If you mean web site
You can go to your profile and put in the url of your site in your sig and as long as it isn't an obscene site, you can keep it there. [img]smile.gif[/img]
[ url=siteaddress]Name of Site [/url ] with no space between the brackets on either end [img]smile.gif[/img]
Your site will be promoted by anyone reading your posts and some of them will even go check it out.
