from the help file:
/echo [color] [-deghiNtsaqlbfnmr] [#channel|[=]nick] <text>
If a channel/nickname isn't specified, the -s switch echos to the status window, the -d switch echos to the single message window, and the -a switch echos to the currently active window.
so, you can use '/echo -s' to send the message to the current connections status window.
or, if you only want to have one place where all your echo's go, you could open a /window and make /echo redirect all the text using /aline.
