For more info on plugin development, follow me on Twitter! @psnlionking23!

Updates: 10/17/11 - Moved to BukkitDev and planning a big update for all you 6000 downloaders :D

OpChat is a simple plugin that lets you know when the operators of the server are chatting! You can also choose the color you want op's usernames to show as!

Features:

Can turn this functionality on and off through "/opchat on" and "/opchat off".
Now has /color or /colour commands to choose what color you want op's usernames to appear as! (See spoiler below)
Added /opchat help command to see all available colors.

NOTE: On default, OpChat is disabled on server startup, so use '/opchat on' to enable it. (Fixing because I think you guys might want it enabled on startup...)

Instant Downloads:

Download OpChat v1.2 [mediafire] (with commands to set your desired color.)
Download OpChat v1.0 [mediafire] (with Op usernames being only aqua.)
Source Code for v1.2 (Link Broken)
OVER 6000 TOTAL DOWNLOADS!!!

Known Issues:

No enable on startup (Fixing)
Saving previous color settings (Working on it, might take a while.)
