I have an article directory site in which I have installed a basic comments system so that users may comment on each article. There is an MySQL error which appears. It doesn't affect the functioning, but it needs fixing.
Additionally, I would like the comments function to be tied into the existing user registration/login system so that people have to register before they can comment.
The whole system is based on LAMP and some javascript.

I would also like some idea of the cost of providing further user features such as home page, blog, email etc. If you can give some idea of the cost and complexity of such additions that would be great.
