Actually I would shorten the advice to "dont release your first map here."

I just went straight ahead and released my first map anyway because I
get by just fine as an outsider of the notoriously elitest, po-faced, bug up
the arse Halo CE community. I for one will miss it when it's gone on may
8th, but don't worry I'll be ok again by may 9th.

OMG, ONLY JOKING!!

real advice....It's a lot smarter to just post pics and seek advice on what
to do / not to do next. theres no reason to release a test map, which is
basically what a box map is.
