In SO beta version, chat does not persist. For example, you start a chat with somebody, go to site, click document library, chat diaglog goes away. James Min, liferay Consultant, informed that, it was an issue in previous version of liferay portal, which is fixed now. But this issue is still in SO 1.5 beta version.
Please provide a work around.
Also can we 3 way chat like conference feature in yahoo/google. This is not as critical as the above issue
