The "start session" and "join session" in linux version 0.88(3753) are not shown under "File" menu.
I tried in Ubuntu 8.10 and 9.10.

Does it mean, this session feature is not available in linux version?

Thanks, Waluyo

Yes, true. This feature cannot be implemented for Linux version, at least, for now.
