How do I create an easily accessible directory outside of /Users/? I want to sync/backup my entire Home (/Users/) directory to other computers using Bittorrent Sync.  Right now my Home directory contains my DropBox folder, which (at 17GB) I do not want to be part of this sync/backup.

I thought an easy way to do this would be to create a Dropbox directory at the /Users level, but even after I set the permissions of that directory to 777, the Dropbox app won't let me move Dropbox there.

I understand that an alternative is to exclude just the Dropbox directory from the Bittorrent Sync (I assume that's possible - I haven't tried it yet), but I think it would be cleaner to have an easily accessible but separate (outside my Home) directory. Is there any way to do this?
I changed my Dropbox directory to /links/Dropbox with no problems the Dropbox app created a subdirectory Dropbox there. I created this directory with New Folder from the Finder
