adding to bookmarks
I think that when sbd wants to exit my site, it can be good idea to ask him if he want to add my site to bookmarks...but I have no idea how to di it, or it can be done at all. What do you think? I've seen sth like that, on some data recovery corp. site. Here is link to these site :http://www.salvagedata.com
I would be wary of interrupting the user's browsing. Let them use the browser's built in bookmarking. By forcing the issue you run the risk of annoying them rather than helping. They may not want to bookmark your site after that.
