I have a requirement for some 'download' type adverts, could anyone tell me whih company is best to use ?

A few years back i used to use a company where you could pick exactly what ad you wanted to use but can't remember which one it was

Any help will be greatly appreciated

cheers

Well i've been doing a little searching and found adbrite, when i tried to create an account it said i already had one, i requested a password reminder. When i loggin in it has £23 in the account from 2006 !! i wonder if they'll pay me interest I can only dream about how popular the forum i created in 2005 would have been if i had stuck at it
ah well
