[n-o-l-o]

I did a workaround by adding this to cmdFlop15:

new szUserName[33];
get_user_name(id, szUserName, 32);

new szMessage[164];
format(szMessage, 163, "^x03%s ^x01: ^x04/flop15", szUserName);

message_begin(MSG_ONE, get_user_msgid("SayText"), {0,0,0}, id);
write_byte(id);
write_string(szMessage);
message_end();

If you know another way how to solve the problem let me know. Thx.
