Latif, Not a problem. I'm happy to see all of you playing around with the system already.
I believe you resolved the conference.chat problem, but just for the sake of pointing it out for the rest of the list, the system is hosted at chat.aditi.lindenlab.com, not conference.chat. I'll bring up the authentication issue internally as well. I'm curious what the root cause may be. Can you be more specific as to how you observed auth taking a long time? I'd like to try myself for comparison. Otherwise, the next step is getting this project viewer together for all of you and starting to test it out :) - Gez On Tue, Feb 1, 2011 at 12:48 PM, Latif Khalifa <lati...@streamgrid.net>wrote: > Gez, > > Thank you very much for such a fast response.
