1. Navbar template:
Code:
<input type="checkbox" name="cookieuser" value="1" checked="checked" tabindex="103" id="cb_cookieuser_navbar" accesskey="c" />$vbphrase[remember_me]
add the red. Nvm.. didn't read your 1st question fully..
STANDARD_ERROR_LOGIN:
Code:
<input type="checkbox" checked="checked" name="cookieuser" value="1" id="cb_cookieuser" tabindex="1" />$vbphrase[remember_me]</label>
2. In "User Profile Fields" in the AdminCP select whatever type of box, fill out the info, and in the "
Field Required" section choose "No, but display at registration" (I'm assuming that's what you want since you said "can fill out" not "must fill out"

)
