1.3 Bukkit Server - Something wierd.

So. Over the last few days I have opened a server, and I have been getting a lot of users. But 2 users came on.. They didn't change their prefix but their chat. Like this: <iAutomatic>: HI <-

The "HI" was in colors, underlined and Bold. I didn't know how they did that.. So, I temporarily banned them.
Here are my Plugins:

Code:

[INFO] Plugins (24): KingOfTheLadder, iLove, UltimateArena, GroupManager
Worldedit, BlazeOfGlory, Vault, SafeCreeper, WorldGuard, iConomy, marriage, Estate, DungeonBuilder, MobArena, NoSpawn, AutoAnnouncer, Essentials, Residence, EssentialsSpawn, DeathControl, Chestshop, EssentialsChat, AntiCheat

 

Have you tried using color codes in chat?

Try typing this without quotes in chat "&aHello testing colors."

I suspect one of your plugins has enabled color codes, which can be very useful. I haven't used it but EssentialsChat sticks out to me.

 

Thank You! That was the problem, Do you have any idea how to disable it for users?

But anyway, I am VERY thankful!

 

Don't give them the chat colour/format/magic permissions: http://wiki.ess3.net/doc/permissions
