Into your loop $team get musername style with:

PHP Code:

$team['username'] = fetch_musername($team); 


Use this before to fetch template bits

Another fix:
Template Cache
for use template cache create new plugin, select SiteTeam Product, set name of plugin example "SiteTeam - Cache Templates", select "cache_templates" hook and into codebox insert:

PHP Code:

$globaltemplates = array_merge($globaltemplates, array('postbit_onlinestatus', 'siteteam_main', 'siteteam_teambits')); 


This use now 100% all features of vb 3.7 ^_^
Thanks
