Domain Mapping confirmation?

hi all,

so... i installed domain mapping... i was wondering.. after you add a custom domain.. is there some sort of confirmation that happens or does it list the mapped domain somewhere in tools>domain mapping page?

after i add the domain to map the page remains the same (see attached screen shot)

also.. is there a secret to getting this to work properly with hostgator? i have set the A record for the domain i am trying to map in godaddy... and have followed all steps in set up.. but it doesn't work.

could it be it isn't resolving yet?
