This might be a stupid question but here goes. I find that a site is linking to mine using a link that looks like this: "http://www.othersite.com/enlace.php?url="http://mysite.com&etc..." and my site opens up in a frame on www.othersite.com. Does this harm my site in anyway? thanks in advance
No, it won't harm it as such. You can easily place some framebreaker code so your site automatically escapes them. Jay
