But I'm not successful that makes me barely anything to brag about and now I'm only riding on previous successes. The sites I run are using a free script that I have heavily modified to fix bug issues and I maintain a list of plugins.
The fact I have heavily modified my script and maintain a code base of plugins is the only reason I have my traffic, the traffic I have returns every day like clockwork, so they must like my site. But It require extensive knowledge of PHP to modify my websites, and also of server jargon to optimize my server to handle the traffic. I'm not going to agree that you can get by without knowing technical jargon like computer languages. Even if you are using a free script your going to have do something with it. :)
