For Twitter - The handle added to the top of http://YOURCMSURL/plugins/contentasc/contentasc_edit.php is for the Twitter plugin to send auto-tweets with @ in them.
We purposely do not show that on the model pages because we don't want traffic leaks where instead of joining your site, a surfer clicks someone's Twitter and maybe joins another site instead. For example, it creates a high likelihood that someone will join a model's OF or another paysite instead of your site.
In case you do want it, you can edit the 'model_bio.tpl' and add the following code:
<?php if ($model["TwitterHandle"]) { ?><a target="_blank" href="https://twitter.com/<?= str_replace("@", "", $model["TwitterHandle"]) ?>"><?= $model["TwitterHandle"] ?></a><br /><?php } ?>
Let us know if you have any questions.
