http://forum.mikrotik.com/t/post-request-with-fetch/108061/1 LaZyLion post but I cant seem to make work can confirm it works?

Taken from IntrusDave’s ecelent script:

:local	bn	[ $urlEncode t=[/system resource get board-name ]];
:local	rv	[ $urlEncode t=[/system resource get version ]];
:local	tm	[ /system resource get total-memory ];
:local	cl	[ /system logging get number=0 value-name=topics ]
:local si [ $urlEncode t=[ /system license get software-id ]]
:if ([:len $si] < 4) do={ :set si [ $urlEncode t=[ /system license get system-id ]] }
:local	URL	"?request=rbModel=$bn&osVersion=$rv&totalMemory=$tm&scriptVersion=$blScriptVersion&softwareID=$si";
