Long middle name

I can see that English is not your first language, so let me make sure that I understand you.

You said,

Sorry, I understand myself

so I think you mean that you found the controls for the lengths of the fields including the middle name, right?

As for the color of the text, as well as the text itself, you can change that. The color must be changed by copying the supplied css example to your own theme's css file. Simply set color: none to default back to your page's text color. The details are found in the README.txt file.

Please tell me if you have solved your problem, or if you need more help.

I had a problem with the * wrapping to the next line in some cases. I couldn't figure out the CSS to prevent it. Note that I'm not setting the fields to REAL required (HTML value). Instead, due to the complex requirement settings, I'm checking it all during validation. Feel free to change your copy as you wish. You can override the theme functions (see the Drupal Handbook) and the CSS in your own style sheets.

So, you basically had two issues above. The first you fixed, the second I won't be changing, so I'm marking this as fixed.

Actually I guess there were three issues and I forgot about the middle one - the validation problem. Anyway, I'm uploading a new release that should fix the validation. Sorry about that. I was working on cck_address at the same time I was doing cck_fullname and thought I covered validation on both.
