I am designing a member driven website using Dreamweaver 8. I could use some advice. The kind of site I am constructing allows non-members to browse, but they will be prompted to register if they are first time visitor or sign in if they are return visitors, this could either be done from the home page, check out page or browsing product page. How can I use OS to accomplish this (someone told me I could us OScommerce, but I know nothing about the use of OS, totally new). Is there any webhosting company that are reasonably price that could assist me?
