62657 poster script mod_rewrite

What I would like is this poster affiliate php script to be setup for mod_rewrite to html to be indexable on the categorys, site map, author links and so on. Only on the [login to view URL] strings and etc. What needs to be done is a .htaccess file and a couple of modifications in the php script - one file - for this to be dispayed properly. Please advise if you can do this. Thank you.
