Gary-Alan:

Yes, I have found myself drastically changing site designs in mid-stream for one reason or another. I tend to dismiss it as part of the creative process although it can be frustrating and time consuming. So hang in there.

I am the volunteer webmaster for a couple of very simple community (non-adult) oriented sites. I was intimidated at first but just dove in and learned along the journey. I am still learning and changing the way I view and build sites. It is part of the process for me anyway. Those experiences pay off for me down the road when I to transfer my curiosity and knowledge to my revenue generating projects.
