HI There What I want to do is use one domain with one installation of wp. Then I have different topics that I want to use a different theme for each topic. Is it possible to do this with only one instance of wp. Has anyone seen any documentation about this. If it is not possible, does that mean I would have to install wp in folders as many times as I have topics. So 8 topics - 8 folders with wp installed in each. thx a lot for the advice
