Alternatively, if you have a twitter account associated with your site you could show friends/followers updates from that to everyone and remove the need for the profile fields.
Code:
<vb:if condition="THIS_SCRIPT == 'index'">
<!-- what's going on box -->
<div id="wgo" class="collapse wgo_block block">
<h2 class="blockhead">My Twitter Friends Updates</h2>
<div class="blockbody formcontrols floatcontainer">
<div class="blockbody subsection userprof_content userprof_content_border" style="width:100%">
<div class="twitter-friends" options="{
username:'twitteraccount',
friends:1,
tweet:1,
header:'<a href=\'_tp_\' title=\'follow me\'><img src=\'_ti_\'/></a><h2>_fr_ Friends / _fo_ Followers</h2>',
loop:1,
users:50,
user_animate:'width'
}"></div></div></div></div></vb:if>
Replacing
twitteraccount with the account name ie
www.twitter.com/twitteraccount
