Sorry, I lost my internet connection for a couple hours. Anyway, I copied your plugin code to create a new plugin using hook member_complete, and I created a template called memberinfo_block_test using the code from the guide page you linked to, but I get a blank tab. I haven't had a chance to figure out why yet.

Are you seeing anything from your template? I think I might have been wrong about using $prepared, I think you might want to use $userdata instead. So maybe change the added line to:

$templater->register('userinfo', $userinfo);

then use {userinfo.field8}, etc. But if you're having the same issue I am with the tab being entirely blank then you probably still won't see the profile fields.
