[Chimera-users] Collaboratory tool removed ?

Hello, I recently noticed that the current production version of Chimera (v1 build 2470) does not have the "Collaboratory tool" anymore. I wanted to give it a try and I am quite disappointed. From a previous changelog (http://www.cgl.ucsf.edu/chimera/docs/relnotes/1.2417.html), I read that "Collaboratory removed (use version 1.2309 for this tool)". My question is: can we expect this feature to be back one day, or should I look for an alternative ? Thanks, Aurélien.
