Suppose i have different categories of advertisements on my site for eg.

         

                      1.Clothes.

                      2.Bags.

                      3.Shoes.

                      4.Cigars.

                      5.Liquor. etc.

 

  i want my site to be customised by the user as to what ads' he/she wants 

to see.for eg.A user doesn't want to see the ads' involving cigars.He 

should be relieved of that kinds of ads'.



Can i do it?
