How can I share my Halo Reach Forge made maps to other profiles on the same console?

[jay]

Here's the scenario:

I made a map on Forge in Halo Reach with Profile "A". How can I share it with Profile "B", "C", etc etc.

NOTE: Profile A is an Xbox Live Gold Account while the rest of the accounts are offline gamer profiles (i.e other friends)

Thanks :-bd
