I am a self taught dreamweaver user and can build a site quite easily. I now need to create registration and login pages for my site, with only members being able to access their own page. I have MySQL set up on my host, but know no more - i dont even know what mysql is???...Am I out of my depth or is there anyone able to offer free help to me.....I didnt really understand the dreamweaver help. Thanks Karl
