I am checking out an affiliate program atm, where basically I just post the link to the main website (a well known website that offers a free service) with my tracker id and people sign up, I earn commission. So it isn't like I'm sending people to some corny sales page but I just need to be able to send them to the main website with my tracker code.

do you know any social bookmarking websites where I might be able to pull this off ? most either show people the full url (would see my tracking id) or check for affiliate links.

I have a blog in which I write a lot about the product because it is a product I use to make money, but I definitely could use help finding other places to post my links.
