in Postbit Templates - postbit add $onlinestatus above Registerd .. if that's where you want it.
Save that, then go to the postbit_online and replace the text there with something like this ..
Code:
<div align="absmiddle">$post[username] is online now</div>
That should give you a "the username" is online .. if that user is online .. just above the registerd date.
Do the same with postbit_offline - remember to edit the text to say offline.
Correct me if I'm wrong
