[Sugar-devel] feedback from a teacher in Uruguay

[David Van Assche]

Hi Andrés,
  The sharing of activities not working for more than a few connections is a
common issue in all the deployments I have seen. It is really important to
have an ejabberd server to help with routing xmpp traffic, if you plan on
running more than a few XOs in collaborative mode.

kind regards,
David Van Assche
