About positioning of QR code, I use this:

<vb:if condition="$post['isfirstshown']">	
<div align="right"><b>Share thread with your friends:</b><br />
{vb:raw thread.qr}
</div>
</vb:if>

Condition is that QR code is shown only in first posts, you can place this code wherever you like it in your postbit (legacy) template. I placed it after signature (but outside of signature conditionals so it's shown even if user don't uses signature).

To use it you need to change plugin hook location as nhawk suggested, from showthread_complete to showthread_postbit_create. But, new template hook that nhawk suggested ({vb:raw template_hook.share_this_thread}) doesn't work, so you don't need to add it at the end of plugin code:

PHP Code:

$template_hook['share_this_thread'] = $threadinfo['qr']; 


It works without it, just use {vb:raw thread.qr} instead.

Important note: If you use it in ad templates, then you need to create this template hook and use it as nhawk suggested. This information is only if you want to manually place QR code somewhere in your postbit (legacy) templates.
