Believe you would need the script for [say command Have not seen this script updated and posted here, I'm sure if you search runuo you should be able to find it.
Thanks! now works!
for those who had the same problem in the future:
1) http://www.runuo.com/community/threads/say-command-help.55242/
2) insert this using: using Server.Commands;
3) change on line21 this "Server.Commands.Register" with-->
CommandSystem.Register
