My Website Membership program

I am developing a new program for my website, wow300.web44.net. It's a simple membership program.

I have been thinking it's a big help if users can help developing the website. And I may even make a self-sustaining website once the traffic inflates. I have made two object classes, a visitor class and a member class, the member class extends the first one.

It took me 2 and half hour, to make it work. Next I will be designing the GUI for the users. As of now, I think it's a real good and convenient program, I can import it to my other website in the future. I have used a pattern I read about, the singleton.

Anyway I have been practicing to have a cleaner codes in the sense that I am now putting spaces between equal signs, the function arguments and the parenthesis. But sometimes I am still doubting if I am doing a better habit or it's just a step back.

But I am sure that I am doing better on naming variables. From one letter variables, I am now using better names and as much as possible I am using English words with right spellings.

It's really hard to be a lone programmer, I hope someone would give me a distinct direction in the future. Maybe my boss in the future, or anyone with more experience.
