"Conference Room" and "Water Cooler" are good choices. Let's also remember the content... not that we have a lot of secure stuff, but let's remember that "Water Cooler" is guest-accessible. In the future, we may want to confine discussion of sensitive operations to the Secure/Verified chatroom. Of course, that ties back around to the (Admin - Diplomat - Intern - Verified - Non-Verified) rank continuum.
We've experienced a flood of members, both new & newly minted "Verifieds". The latest of these is CMDR Gabriel Case (gcase); I'd like to congratulate gcase on his promotion, outstanding work with SI Terraforming and SINC projects, and larger involvement in this community.
