also, i was wondering what the upload process to the forums is

There's no building limitations.

All you have to do is submit it into the Maps submission section.

If you need any further help involving uploading PM me.

finally, i was wondering if you guys create the borders or if i have to

You could take a video of the map.
Alternately you can also provide screenshots.

The iron bars are technically optional. All it does is set the edges.

You can create borders with world edit.

You're welcome
