you dont actually put them anywhere becuase they were commands you can just type
try typing this in
/alias autotalk if (($1 ischan) && ($2 isnum 1-)) { .timer.autotalk 0 $calc($2 * 60) if ($( $+ $1 $+ ,) ischan) $({,) msg $!( $+ $1 $+ ,) $3- $(},) }
if your having to type it is ctrl-o
once thats typed in exactly as it is, you have an added command
/autotalk <channel> <minutes> [text]
You well say a blank line or optionally [text] in <channel> once every <minutes>
