Hi,
Thanks for that. I thought i had been penalised but today i did some reading and read that if i had a penalty, yahoo deindexes all your pages except for the homepage, and it’s indexing both my sites quite well…maybe i just need to seo it better. if anyone could give me some good advice on yahoo then i’d really appreciate it 
but even so, i guess it’s better to hide the affiliate links as i have also read G and Y hate them. Is it best to hide them by using a tracking page with a variable or a redirect, i.e, by sending them to a folder which has a 301 redirect (such as /thiscasino/ which then contains and index page with a 301 redirect)?
