Making Your Own Maps and Playing them on XBL

Okay , I just went to www.halomaps.com and followed their tutorial on how to make your own maps and so I did and it has its own name(DrXthirst's Map) and its own description. And I was wondering if I played this on XBL if others could play it and/or see the description and name of it. Thanks for any answers you can give , DrXthirst.

 

they cant play it but i think they can read the descritpion

 

Cool , I will see if it works , but if it dont , oh well
