Simplified Registration

Can someone point me to a way to simplify the registration form. All I want initially is just user name, email, password, and city. Takes too long to fill out the form and people quit part way through or after a field like zip code is not filled in.

You can edit the join form from administration, builders, profile fields, which will take you directly to the editing screen for the join form. You can also toggle through other profile-related pages to edit from here.

Thank you...

Along the same lines, which language key do I need to modify to change the text for "Man" and "Woman" to "Male" and "Female" on _ONLY_ the join and profile pages where the user chooses if they are male or female? I would still like to have the options be man/woman for the "Looking for" values.  Thank you!

I believe it's universal, so you'll have to make two new language keys for this (which can be done from administration, settings, languages) and then edit those items for those pages to use the new language key.
