works fine and is easy to use.
But it does NOT seem to SYNC across machines. Or am i doing something wrong?
Installed TBSYNC + CalDav/CardDav+ Catagory Manager on multiple machines, and using the same Google Account.
I created categories on one machine, they do not sync to the other ones.
any possibility to do that?

Sadly google sucks, they did not implement the full CardDAV spec and do not sync these groups/categories. They only do that in their own proprietary google API (which TbSync is not using). Any other CardDAV provider will do.
