his script could be for any room really but is nice to have at the gate.  Just change the pass1, pass2, etc to whatever password you choose and the set of numbers are the room ids that you want to be transported to.

ON OUTCHAT {
{ "$1" GREPSUB pw =
{ dta =
{ dta 1 GET GOTOROOM
} pw dta 0 GET == IF 
} 
[ [ "pass1" 999 ]
[ "pass2" 716 ]
[ "pass3" 724 ]
[ "pass4" 114 ]
] FOREACH
} CHATSTR "^(.*)$" GREPSTR IF
}

Different one

ON OUTCHAT {
{ "" CHATSTR = 150 GOTOROOM } CHATSTR "PASSWORD" == IF 
{ "" CHATSTR = 151 GOTOROOM } CHATSTR "PASSWORD2" = = IF 
{ "" CHATSTR = 152 GOTOROOM } CHATSTR "PASSWORD"3 = = IF 
{ "" CHATSTR = 153 GOTOROOM } CHATSTR "PASSWORD4" == IF
}
