Thanks for your reply Ray.
Unfortunately the reseller system from my hosting provider requires FTPES connection which is something Dreamweaver doesn't support.
Currently I have set up clients live site which is using PowerCMS but they are now wanting to explore add secure area hence am looking at security assist.
i suppose what I am trying to get at is is it possible, bearing in mind the above, to create a local based security assist setup and then 'merge' that into the live site which is already using powercms? and can the local files be FTP'd using something like Filezilla or does it havre to be through Dreamweaver?
