I would like to know how to add fields to the registration page such as city and state?
I do not know how to write php or anything else in regards to development. I know basic html and that's why I am using a program like this to create my website. This is the only feature I see K2 missing. Other than that I am enjoying the program.

Thank you to whoever may answer this question.

You can just have people register through the normal Joomla registration page.

not yet possible with version 2.1, AFAIK. maybe in the future. you can directly edit joomla user database or use community builder.

Or use Chronoforms and connect the form to the Joomla registration process.
