I got it to work.

config on the slaves:
- You need to add the "master" to the client accounts as being allowed
- you need to allow the content to be shared on the slaves.

on the master:

then request shareing on slave account 1. You need to specify an accountname!! (can be whatever)

request shareing. you get then an INDEX. there you need to specify what you want to import into the masters database. (or use the plus and the marker in the top row to mark all (press the red plus button again so see if everything is checked)

after you specify what you want to get press the get button again and it starts transfering.

When you have it once you can right click on the account and request from the same toon again.

easy cake.

(sometimes the interface gets messed up just /rl and it is fine again)

cheers
