[Sinecure]

Its actually just a simple templae modificiation.

Go to your admin panel, then go to the templates section.
You are going to need to modify the following templates.
Postbit
Postbit_offline
Postbit_online

First off change the postbit_offline template to the following:

<b>Offline!</b>

Second, change postbit_online to the following:

<b>Online!</b>

Now comes the tricky part. Open up the postbit template.
About 3 quarters of the way down you will see a variable called $onlinestatus. Cut it from there. Then scroll up until you see the following:

<smallfont>Registered: $post[joindate]<br>
	Location: $post[field2]<br>
	Posts: $post[posts]</smallfont>

Replace that code with the following:

<smallfont>$onlinestatus<br>Registered: $post[joindate]<br>
	Location: $post[field2]<br>
	Posts: $post[posts]</smallfont>

That should work perfectly, if you have any troubles let me know.
