Seeing Html Code On My Posts – But Don’t Want To

Hi,

I have used several blog posting clients, including BlogDesk, W.Blogg and even MS Word 2007. They all publish my posts but when I go to view my blog I can see the html code on the posts.

I have tried to keep the post as html free as possible but I see a
p before each paragraph and a br / at the end of each line, is there something I need to set in the settings of the blog admin?

Thanks for any advice
