Yeh..Its not so easy to run a site and the site which is Paid sites..you have to manage everything...from the top to bottom and you have to look after your site as well as your members whether they need something or not whether they are happy with your site or not these are the main criteria of a admin but all admins are not the same some are very arrogant and threat its member as slave and some admins are very nice like DINO (Web-Money Admin) and i know its very difficult to earn from any online sponsors and maximum of paid sites except affiliate and adult are paying from their pocket the profit margin is very less.
Thanks.
