Problems syncing folders with color tags (osx)

Hi all
I bought a ex4100 which is connected to our network with 4 mac computers. All wired with a 1gb router, and cabled.
I installed wdsync on all computers, and all read and write files on the sane folders. This works fine.
The problem I found is that I use color tags (which help in order to classify folders) and these tags do not get synced.
Before we bought the ex4100, I had all computers synced with dropbox, which also synced the color tags.
Is there any way to sync those tags with wdsync?
Thanks!
