Not sure where to put this since it probably doesn't really count as an actual modification. Just a custom BB code I developed for my moderators. Thought there might be someone else out in vbland that might want to also put it to use.
BB invocation code is whatever you define it to be in admincp > CustomBBCodes. Create a new bbcode, name it, paste the following code into the "Replacement" box.
Code:
<center>
<table border="0" cellpadding="5" cellspacing="0" width="600">
<tr><td align="left" valign="top" width="100">
<img src="http://i55.tinypic.com/qxl54z.png" height="150"></img><br>
</td><td align="left" valign="top" width="400">
<center><div style="width:400px;height:150px;
border:1px solid black;padding:5px;bgcolor="#ffffff">
<font color="darkblue"><b>Moderator Message:</b></font><br><hr>
<b>{param}</b>
</div><br></center>
</td><td align="left" valign="top" width="100">
<img src="http://i54.tinypic.com/w1yfk.png" height="150"></img>
</td></tr></table></center>
Save the BB code and then you're done. Also attaching a 21 x 20 px hat image if you want a button on your editor controls. I used
Advanced BB Code Permissions to only make modhat available to mods and admins on my board.
See attached image.
