I have small problem. I want sponsor web accounts and place for interesting sites. But I also want that on every site that is sponsored open popup. I'm thinking to auto attach some code to each sites throught htaccess or sth else on server side. I don't know ... maybe you could suggest me some solution to this.
I only want to auto open popup for each new visitor on sponsored sites - without any modification on sponsorred sites.
I have my own dedicated server with cPanel then I think that if it's necessary any system modification are possible.
