I have tested it with EssentialsChat and mChat. If you try to use &3 to make the tag a color instead of it changing the text color it just addes &3 (same on all colors) to the beginning of your tag and makes it default color. With mChat its messed up in the /clan list page but its ok when you actually chat.

Can you show me how you are using &3? Where are you adding that? In the configuration? On a specific command?

its during the clan creation so an exampl would be

/clan create &3test test
and it says
[&3test] test clan created
and it looks that way when you do /clan list and chat with essentialschat but with mchat it looks ok when you actually start chatting and once you reload the server it looks right in the /clan list with mchat it never looks right with essentialschat (which i could care less if it works with that on (: )

oops hit wrong button reopening

You change the tag color with the command /clan modtag , and dont add the colorcode during clan creation.

EssentialsChat will not be supported by SimpleClans
