To begin, when I say "is it possible," I mean can a newbie web designer like myself accomplish this without much trouble...And if possible, it would be wonderful if anyone could point me in the right direction in terms of what software to use, what host to use, etc... What I want to do: I want to create a web site (most likely through iWeb being that I have little experience with web design, but I do consider myself computer savvy). What I want with this site is for a form of public blog geared towards a specific topic. I would like for the layout to be relatively simple (basically a box for a post in the middle of the homepage) where someone posts thoughts and other users can respond to that thought creating a "conversation." I would like for visitors to create user accounts, along with profiles, avatars for posting. Im not sure if there is a service out there that can support a blog like this (either free or low cost). Any help and further questions on this is greatly appreciated!
