I'm NEW to K2
I'm going to add fields to the Users. Do I add the fields on Joomla or K2???

If in joomla, one of the fields is Gender, and K2 already asks for it. Do I have to make the dual entry??
Also if in Joomla. do the extra fields are added to K2?? Or the extra fields have to be managed through Joomla users.

If in K2, how I add the extra fields.

I need to understand if I'll manage users through Joomla and use K2 user login just to use K2 story?????

Fields needed are: Phone, Town, Sex, How you new about us and the Motorcycle, since it is a motorcycle group.
